Quick Overview

Why does BRS recommend this?

BRS Reef Saver Live Rock is one of the most unique rocks that is available on the market today.  Reef Saver is not taken directly from the ocean, and does not impact living coral reef structures in any form.  It is always 100% free of nuisance algae or any type of pests.  

BRS Reef Saver rock is one of the easiest rocks to work with when aquascaping new tanks or adding more rock to an established tank.

BRS recommends curing all rock before being used in an established system.


Full Details

BRS Reef Saver Dry Aquarium Live Rock can be shipped to Canada.


BRS Reef Saver Dry Aquarium Live Rock, our environmentally friendly rock, works great for aquascaping. This rock is 100% free of nuisance algae and pests which can cause complete tank shut downs and is guaranteed to be free of apitasia, bubble algae, parasitic isopods, mantis shrimp, acro eating flat worms, little red bugs, fire worms, predatory nudibranchs, pyramidellid snails and other common pests. BRS Reef Saver rock comes in unique shapes that fit well together to make interesting and unique structures. BRS Reef Saver Rock arrives at our warehouse pre-soaked and rinsed. This is by far our cleanest rock.


How much rock do I need?

Knowing exactly how much Dry Live Rock you will need can be one of the hardest questions to answer since every tank and rock will be slightly different. A general guideline for Reef Saver Dry Live Rock, we suggest 3/4 to 1 pound of rock per gallon of display tank volume and may vary depending on your overall goal for the aquascape. We always recommend purchasing a little extra dry rock to ensure that you will have enough to complete the aquascape you are looking for, any extra rock can always be broken up and placed in your refugium, overflows, and sump for added filtration.


BRS makes every effort to securely pack the Rock.  However, the UPS automation is not always gentle on heavy products like this and they do not consider this product insurable. Because of this, there is some inherent risk with shipping rock like this across the country and it is impossible to replace or refund broken pieces. If this happens most pieces can be repaired with epoxy.

  • Worth the money! By Wally on 10/30/2017

    Easy to use, free from pests, and aesthetically pleasing. I'd definitely recommend cooking this rock, or at the very least using it accompanied with live rock. Great stuff!
  • The Best By Raymond on 10/29/2017

    This rock is amazing and beautiful, especially at its price. Fits together incredibly well
  • Worse than Swiss Cheese By Tim on 10/25/2017

    Not sure if this applies to all pieces of Reef Saver Rock, but my order was as follows

    The Reef Saver rock has a host of problems in my opinion. First, it was shipped full of dust. I suspect I was getting the "bottom of the barrel" but still. Soaking for hours and I still find cakes of mud. Second, it is too porous and soft. Picking up pieces with my fingers and it begins to crack off. Forget about trying to build pillars or stacking. And third, all of the pieces I ordered are worse than swiss cheese. The entire surface is covered in holes larger than 2-3" diameter. I can already see the detritus build-up in the holes that surround the entire piece of rock.

    I much prefer the Pukani I was also shipped. Unless you are looking for rock that washes up on the beach after tumbling for years on end, look over Reef Saver.
  • Love it By richard on 10/16/2017

    Built part of my reef in 2011 with this love it and very cheap
  • Great Rock & Pricing By Bryan on 9/26/2017

    I was between this, and the pukani and I am really happy I chose the reef saver rock. Great customer service! They were very attentive to our comments (If you have a certain size request, let them know in the checkout comments!) Can't wait to aquascape with them!
  • Good rock for the price By Jace h. on 9/20/2017

    I have had this rock in 2 of my tanks and each times it's been great ! Cutting and drilling is a bit of a pain, but just use a tile saw and some water and it cuts up nicely, I've always made sure to soak it in RODI for a week then in heater saltwater for a week , probs over kill but can be too careful, plus it saves on dust
  • Saves the reef but that's about it By nubbia on 9/11/2017

    Ordered 20 lbs of reef saver a few weeks ago, specifying in the order that I'd like a mix of small pieces as I'm setting up a nano tank.

    Let's start with the good: rock was well packed, only a few small pieces broke off. Also, it has minimal environmental impact which was the most important thing for me.

    The bad: Despite my request, I got two massive pieces and one medium sized one. Zero aquascaping potential, had to stick the three pieces in the tank as they were. Also, the rock I got is significantly less porous than what's on the pictures here.

    Overall, I would think twice before ordering again
  • Great rock By jason on 8/25/2017

    Great quality dry rock came in nice sizes not small chunks and very speedy delivery with the free shipping
  • Very nice rock By farcluun on 7/30/2017

    Now turned into live rock, fit well with my existing rock. Very happy.
  • porous clean rock By Traclly on 7/26/2017

    if you are looking for porous clean rock I suggest this. I was happy with it.
  • Very happy with the rock good size packaged well good price By Julie on 7/22/2017

    Very happy with the rock good size packaged well good price
  • Worth the 2.59 By Jarod on 7/19/2017

    I ordered 45 lbs of this to set up my new Red Sea and honestly the only complaint I have is that I didn't request smaller sizes.. I received about 3 football size rocks and 3 2x softball sizes. For the price I'm not expecting glamorous rock but I expect some quality. And this hits the spot, easy to stack and give some interesting aquascape design possibilities since u can almost always find a place to rest it in

Hi there,
What is the recommended amount of rock per gallon? I'm aquascaping a JBJ 28 LED tank. thanks!
Question by: Chris on Sep 30, 2013 8:07:00 AM
Hey Chris,
We recommend a pound per gallon as a good ballpark place to start. It will give a nice middle of the road aqua-scape and is what most folks are looking for!
Answer by: Bulk Reef Supply on Sep 30, 2013 8:07:00 AM
I'm setting up a 35 gallon 20inX20in cube, out of the three pukani, reef saver or Fiji which offers the smaller pieces my tank requires for me to get the best results aquascaping? Thanks!
Question by: Kyle on Nov 22, 2013 8:48:00 PM
Hi Kyle,
Fiji and Reef Saver offer the smallest size pieces. Personally I prefer reefsaver in these types of situations as it is really easy to stack and create your aquascape.
Answer by: Bulk Reef Supply on Nov 22, 2013 8:48:00 PM
Is the price shown here the price per pound? Thanks.
Question by: Steve on Sep 5, 2013 6:11:00 PM
Hi Steve,
Yes the rock is sold by the pound, so the quantity you enter in the quantity field is the number of pounds you are ordering.
Answer by: Bulk Reef Supply on Sep 5, 2013 6:11:00 PM
Hi, I am looking into getting into a reef tank. I understand I need to cure the rock, but could I keep fish during the process? Also, would 60 pounds of reef saver be a good amount for a 40 breeder?
Question by: Ethan Wood on Apr 10, 2016 4:52:00 AM
Great question!
You will not be able to keep fish with curing rock as the nutrient levels will fluctuate too much. Around 40 lbs would be recommended for weight. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 13, 2016 6:57:00 PM
Do the rock come in certain sizes or just random?
Question by: Bobby on Feb 9, 2014 6:38:00 PM
Hi Bobby,
There made by nature so they are like snowflakes, each piece is entirely different, though most range in the softball to football size.
Answer by: Bulk Reef Supply on Feb 9, 2014 6:38:00 PM
What is the weight of one rock?
Question by: Logan on Apr 25, 2016 11:42:00 AM
Great question!
It will range by size of the pieces however on average a football sized piece will be 5 lbs.
Answer by: Connor (Admin) on Apr 27, 2016 2:44:00 PM
I've just read a couple of articles saying that this rock has phosphates in it and to give it a Muriatic acid bath followed a Lanthanum Chloride treatment, is all this really necessary?
Question by: Vinny on Mar 30, 2016 7:22:00 AM
Great question!
You will not need any acid or other treatment for the rock. By curing the rock in heated saltwater for 6-8 weeks you can remove all dead and decaying elements (Phosphate is not "In" the rock rather it is part of the dead and decaying elements) Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 31, 2016 7:06:00 PM
I am setting up a new tank and will add the rock with live sand and water at the same time. Can I just put this rock directly from the box into the tank without curing in water for a couple of weeks? Thanks,
Question by: Jonathon C on Mar 17, 2016 1:09:00 PM
Great question!
You certainly can cure the rock in the tank without much issue. You will want the rock to sit in the tank with no lights and high flow for 4-8 weeks. After which you can perform massive water changes of 100% and ensure the nitrogen cycle has begun. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 18, 2016 9:53:00 AM
Is the price for the rock for a piece or by pound? If so, how big is the piece?
Question by: Frank on Apr 12, 2016 5:38:00 PM
Great question!
All rock is sold by the pound. On average a football sized piece will weigh between 5-10 lbs. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 18, 2016 6:19:00 PM
Do you ship reef saver rocks to Canada? Your website says no tonga, pukari etc.
Question by: Leo on Apr 20, 2014 11:26:00 AM
Hi Leo,
Yes the reef saver rock can be shipped to Canada.
Answer by: Bulk Reef Supply on Apr 20, 2014 11:26:00 AM
Hey guys! I ordered a bit over 30# reef saver for a new tank.
Would it be recommended to toss in a bit of live rock from a local pet store all into the container I'm going to be curing these in?
If yes - is only a heater and a couple powerheads sufficient for equipment, or do I need to introduce a filter now if wet live rock is included?
And lastly - would it make a difference if I include 1lb of live rock vs 5lb? Or only the rate at which the reef saver will become populated?

Question by: Zil on Dec 28, 2016 3:15:00 AM
Great question! You are all over it! Adding a cured/live rock to your curing bucket will act as a seed to bacterial colonies. All you need is circulation and heat to continue and finish the process. :-)
Answer by: Randy (Admin) on Jan 2, 2017 7:52:00 AM
I am starting a new tank with the Reef Saver Dry Live Rock and Caribsea Arag-Alive Fiji pink sand. Should I start the cycle with the sand first while I cure the rock and add the rock later? Or can I start the cycle with both the sand and rock? What is your recommendation?
Question by: Calvin on Apr 23, 2014 3:37:00 AM
Hi Calvin,
If your going to cycle the rock in the tank, I would just do your aquascape, add the sand, add the water, and then let the whole system cycle together.
Answer by: Bulk Reef Supply on Apr 23, 2014 3:37:00 AM
I'm just about ready to put the BRS Reef Saver I bought into my 46gal tank and start the cure and cycle. I'm planning to add a 20lb bag of live sand and a bottle of Bio-Spira as well to give the bacterial growth a jump start. My question is whether I need to add an external source of Ammonium for the cycle on a regular basis? It seems like the bacteria will need something to "eat". (It doesn't seem like BRS Reef Saver, live sand, or Bio-Spira will introduce any sources of nutrients for the bacteria to consume, or will they?)
Question by: Eric Bjorklund on Jan 25, 2017 9:16:00 AM
Hey there! It sounds like you are off to a good start with that game plan! A small bit of fish food would be more than enough to start the cycle and get your tank going. :-)
Answer by: Randy (Admin) on Jan 28, 2017 10:29:00 AM
I have a 75 gallon reef tank with only 60 pounds of live rock I want to buy 50 pounds of reef save dry rock but what is the process to do to add it to my existing tank without a problem
Question by: Christian on Aug 2, 2014 1:59:00 AM
Hi Christian,
The Reef Saver Rock is the cleanest of the rock so you don't have to worry about a cycle when adding it to an existing tank. You will get the best results by giving the rock a bit of a cure before adding it to the tank though. The simplest thing to do is to grab a container large enough to submerge the rock. Fill it up with your rock and some saltwater, throw a heater in it and let it sit for 4-6 weeks.
Answer by: Bulk Reef Supply on Aug 2, 2014 1:59:00 AM
I just received 100 pounds of your Reef saver rock, I am starting a new 180 gallon tank. Was wondering if I can add the rock then add the water and salt and let it cycle from 4 to 6 weeks and then add my fish? after my water has cycled do I need to do a water change how much of a water change do I need to do?also would 100 pounds of rock be sufficient for my 180 gallon tank?
Question by: George millette on Jan 25, 2017 5:01:00 PM
Hey there! It sounds like you have a pretty solid plan of attack and I would recommend the same! 100lbs would give you a nice minimalist aquascape, but if you plan to have a heavy bioload of fish you may need to add more rock or ceramic media. This will allow for more beneficial bacteria to live on the extra surface area. :-)
Answer by: Admin (Admin) on Jan 28, 2017 11:18:00 AM
Because this rock is considered to be devoid of all pests and algae is it still a requirement to cure it prior to beginning to cycling my tank or can I just aqua scape add sand, water and continue on ?
Question by: Chris on Mar 9, 2016 9:41:00 AM
Great question!
You will want to cure the rock still to build up a safe amount of bacteria and remove any dirt and contaminants as it is still removed out of the ground, Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 9, 2016 3:54:00 PM
I am setting up a 120 gal and would like to buy 120lb of reef saver rock. Now if I use the Red Sea reef mature kit or Dr. Tim's bacteria to cycle the tank do I still need to do the 100% water change?
Question by: Michael Eaddy on Apr 3, 2016 10:09:00 PM
Great question!
We recommend curing the rock in a separate container to remove any excess nutrients before placing into the tank and starting the tanks cycle. If you prefer to cure in the tank we recommend curing for the same period and starting the cycle with the mature pro later. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 6, 2016 6:50:00 PM
Hello, i was going to buy some of this rock but i see that it does not display by how many pounds you guys sell it. How many pounds is the rock displayed?
Question by: Max on Jun 13, 2015 5:17:00 PM
Great Question,
We sell all of our rock by the pound. We ask that you give us an estimate of how many lbs of rock you are looking for (Ex. 1 lb per Gallon) The pieces shown in the product photo are not actual pictures of the rock you will receive, more of an idea of shapes and sizes, the typical Reef saver will range between 5-15 lbs for a football sized piece.
Answer by: Connor (Admin) on Jun 15, 2015 4:17:00 PM
My heater malfunctioned and boiled my fish. I decided to upgrade to a 125 gal tank. I removed the rock, which was about 8 years old and put it in a container with water from the tank and aeration. Can I cure my reef saver live rock in the same container with my old rock? If so, then for how long?

Question by: Ellen on May 31, 2017 2:02:00 PM
There isn't necessarily anything wrong with curing the two types of rock together, but it's very likely that the older rock will have significantly more organics accumulated in it which may take longer to finish breaking down. The Reef Saver rock typically has very little organics on it and can be cured and ready to use fairly quickly in comparison.

Happy reefing!
Answer by: Zack (Admin) on Jun 7, 2017 4:16:00 PM
How big is each piece?
Question by: Chad on Mar 17, 2014 4:13:00 PM
Hey Chad,
Each piece is different which is why its sold by the lb. Pretty typical for most pieces to be in softball to football size range with a football size piece weight somewhere in the ball park of 7-8lbs.
Answer by: Bulk Reef Supply on Mar 17, 2014 4:13:00 PM
Hi I'm setting a 20 gal tank. Please recommend the quantity adequate. Can this be shipped to India??
Question by: Conrad on Feb 26, 2016 9:31:00 AM
Great question!
We typically recommend 1 pound per gallon around 20 pounds total. Unfortunately we do not offer international shipping outside of the US and Canada. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Feb 26, 2016 9:39:00 AM
I'm buying the dry live reef saver rock and I don't have the money to buy it all at once. Is it safe for fish or inverts to buy this rock in increments cure them in a separate container or trash can for a month like the video shows then when there done add them to the tank? Just double checking thank you
Question by: Scott Watson on Feb 12, 2017 12:47:00 AM
Hey there, great question! Adding small increments of the Reef Saver rock to an already established aquarium will not negatively affect the tank. The existing rock in the tank will help speed the colonization of the new rock with very minor spikes in ammonia or nitrate. :-)
Answer by: Admin (Admin) on Feb 13, 2017 2:25:00 PM
Where does this come from and what's its make up?
Question by: Donald Bowling on Apr 11, 2017 6:15:00 PM
Hey there,
The great thing about Reef Saver rock is that it is real reef rock. The advantage is that it comes from a land-based dead coral reef that is quarried in the US, so there is no impact to the ocean reef rock, and it's also significantly lower in residual organic material.

Have a great day!
Answer by: Zack (Admin) on Apr 23, 2017 8:23:00 PM
Do you have to cure this rock
Question by: Johnathan on May 22, 2017 11:10:00 PM
While this rock generally requires minimal curing due to the very low organic content, but we always recommend curing any new rock prior to adding to an established tank.

Happy reefing!
Answer by: Zack (Admin) on May 25, 2017 4:31:00 PM
Just bought some of the reef saver rock. What temp should water be to cure. I'm going to be adding these to established reef with existing live rock. I'm going to cure for 3-4 weeks. Should I ever change the curing water while curing? When cure is done, do I just rinse rock off and add to tank or something else?
Question by: stanton on May 13, 2014 11:55:00 AM
Hey Stanton,
I would use water that is the same temperature as you will have the tank at. Pretty good bet that will be somewhere around 78 degrees or so. You don't need to do a water change while curing the rock but you want to get rid of all of that water when your done. If your curing in a separate container you can just move the rock to the tank. If your curing in the tank then do a 100% water change.
Answer by: Bulk Reef Supply on May 13, 2014 11:55:00 AM
Do we type how many pounds we need of the live rock in the quantity feild? Like I would need 20 so I would just Type 20 in the quantity feild and I would get 20 pounds??
Question by: Ben on May 16, 2016 9:00:00 PM
Great question! All of our Dry Live rock is sold by the pound, meaning, quantity entered stands for pounds (lbs). Ex: 20qty = 20lbs :)
Answer by: Carter (Admin) on May 24, 2016 11:24:00 AM
Hello I have the reef saver rock and wanted to know how many pounds to put in 60 gallon tank ?
Question by: Hector on Jun 7, 2014 9:41:00 AM
Hi Hector,
About 60lbs total should be great for a tank that size.
Answer by: Bulk Reef Supply on Jun 7, 2014 9:41:00 AM
Good Morning! I'm wanting to create a couple of islands in my reef tank hopefully creating a "bonsai" look. I've ordered 60 lbs of the reef saver rock and wanted a few of the shelves with the base. But it would only let me order a minimum of 20 lbs which came to almost a $100. Is there any way that I can order less than that? I'm not sure how much 20 lbs of the shelf rock would be and I only wanted a few pieces to add to each island. Thank you for your help~
Question by: Janet on Jan 22, 2014 4:31:00 AM
Hi Janet,
The 20lb minimum isn't because we don't want to let you buy less then 20lbs, its because a single rock weighs atleast 20lbs :-) Rocks with base are typically quiet large so if your looking for smaller/lighter pieces, the pieces without a base will be what your looking for :-)
Answer by: Bulk Reef Supply on Jan 22, 2014 4:31:00 AM
If this is 100% pest free, why does it need to be cured? I am replacing live rock I bought from a LFS in September of 2015 that I have been battling aptasia, bubble algae, and bryopsis with.
Question by: Randy on Jun 23, 2016 9:35:00 PM
Great question! We recommend curing all dry rock in order to establish a good starting population of beneficial bacteria within the pores. :-)
Answer by: Randy (Admin) on Jun 29, 2016 5:35:00 PM
I'm looking to add some dry rock to my existing setup? I will not be removing any of my current live rock I would just be adding the dry rock. So can I just put it right in or is there something I need to do to it first? Thanks for the help........Chris Turo
Question by: Chris T on Mar 31, 2014 1:28:00 PM
Hi Chris,
We would always recommend cycling any rock outside of an existing aquarium before adding to a tank with livestock, though as far as rock goes the Reef Saver rock is by far the cleanest rock out of the box.
Answer by: Bulk Reef Supply on Mar 31, 2014 1:28:00 PM

Whats the average weight per a rock?
Question by: peter on Apr 8, 2016 10:19:00 PM
Great question!
Depending on the size they can typically range from 5 - 10 lbs per piece. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 12, 2016 5:32:00 PM
do you need to cure reef saver rock the same as you would live rock or is it fairly free of organics?
Question by: john on Sep 1, 2013 3:53:00 AM
Hey John,
We would advise cycling any type rock from any source because it just isn't worth the risk of your live stock not too. As far as the rock goes though, the reef saver is by far the cleanest of any of the rocks right off the bat.
Answer by: Bulk Reef Supply on Sep 1, 2013 3:53:00 AM
Howdy y'all, I've seen the video of Ryan chiseling and cutting the Pukani rock. Is the Reef Saver rock as easy to manipulate and cut? Thank you!
Question by: Blake on Oct 4, 2013 11:06:00 AM
Hi Blake,
The Reef Saver rock is much harder and not nearly as easy to manipulate. If you want to chisel out caves and the like I would highly recommend going with the pukani :-)
Answer by: Bulk Reef Supply on Oct 4, 2013 11:06:00 AM
I am in the process of planning a new tank, a JBJ 45 rimless Cube AIO and was wonder what is the recommended amount of rock for a tank this size as well as the correct amount of sand for it. the actual display portion of the tank will be 26 x 16 x 21 I was going to use the ocean direct original grade sand approximately 1- 2 inches deep. Would you recommend another type of rock for this?

Thank you.
Question by: Rob on Dec 23, 2013 1:28:00 AM
Hey Rob,
Great questions. For a tank your size 45-50lbs of rock should be right in the ballpark of what your looking for. Sand wise with the dimensions of your tank, coincidentally your also looking at 45lbs to get you about a 2" sand bed (half as much for a 1" sand bed). With most sands being sold in 20lb or 40lb bags, I would pick up a 40lb bag (or 2x 20lb bags) and you should be in great shape.
Answer by: Bulk Reef Supply on Dec 23, 2013 1:28:00 AM
does this rock have to acclamate
Question by: lynda on Oct 24, 2013 10:26:00 AM
Hi Lynda,
The rock isn't alive so it itself doesn't need to be acclimated. We would however recommend cycling any rock from any source being atleast cycled before adding to an existing aquarium to make sure there isn't any risk to your existing livestock.
