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.
Shipping: 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.
No Hitchhikers By Philip C on 2/2/2019Philip C would recommend this product to a friendI had bought this rock previously and used it in my 30 gallon tank with no pests attached and I got some good pieces, but in my recent order for my 40 gallon tank 35lbs I was not too happy. One of the pieces was this big blob of a rock like a boulder. I busted off a few pieces mostly rubble. had another 3 or 4 smaller pieces so went with them. I went with this rock as rock in my previous 40 gal build and the sand became a haven for Aip Tasia. Got tired of killing them. 3 stars based on previous shipment.
Thanks BRS! By Scuba Steve on 1/4/2019Scuba Steve would recommend this product to a friendI'm an old school reefer.I like my rock to come out of the ocean,but nowadays it's next to impossible to find affordable harvested rock.
I looked around the web and decided to give this a shot.I requested small to medium sized pieces for a RS Max e170 and BRS hooked it up!The sizes were perfect and have tons of character!Very little was broken as BRS really packed the box tight with packing peanuts!
I would highly recommend this!
Good Rock! By Will on 12/20/2018Will would recommend this product to a friendGreat rock for a good price!
Great Rock, but order more than you think By Joshua on 12/12/2018Joshua would recommend this product to a friendThis is a great rock. I ordered 50 pounds of it for my tank and arrived fast and packaged as well as you can expect for rocks. Most of the pieces were a good size and aquascaping this rock was very enjoyable. The rock fits together well and is very stable. I did get some small pieces too. I have had this in my tank for almost 2 years now. I have a 70 gallon display and got some live rock from a friend to seed this. So in total I had about 60 pounds for my 70 gallon tank.
I wish I had got more rock though. This rock is not as porous as other rocks. BRS has some great videos on this and talks about it. So my advice is either order more than you think you need so you get plenty of bacteria. Either add some more rock to your display or put extra in the sump. I am adding some MarinePure blocks to my sump to offset the fact that this rock just doesnt have as much surface area as other rocks.
Still, I am super happy with it when I upgrade my tank I will get more.
successful aquascape By Andrew on 11/4/2018Andrew would recommend this product to a friendAs with the other reviews this thing is great as far as being able to put together pretty seamless formations. I didn't know that splitting it would be pretty simple and the resulting smaller pieces would work as well and look as good as they did. If you do have special request, like I did, to have one large piece in my second order (they shipped 4 small pieces instead) I suggest calling them.
Better to order large quantities By Casey on 11/1/2018Casey would recommend this product to a friendI ordered a small amount (only 12lbs) for a nano tank and the rock was just too big. Got one huge piece which weighed over 10lbs and a small one. Wish I could have gotten more variety but I think ordering such a small quantity was my problem. Will order more to see if I can get some variance.
Good Sustainable Solution By Richard on 9/28/2018Richard would recommend this product to a friendI wanted to finish off a 55 gallon aquascape with 10-15 more pounds of rock. The tank has a mixture of Pukani, Fiji and Reef Saver and while the former look more interesting and are lighter and more porous, the Reef Saver seems to cure quicker and is probably a more sustainable product. After a week in a bucket of saltwater with a powerhead, I didn't get a phosphate reading so in the display they went. So far, so good. BRS sent me three nice big pieces that I am very happy with.
Great Product By Christian on 9/24/2018Christian would recommend this product to a friendLove it! I got my packet in no time and the rocks looks beautiful in my tank! Five starts for their costumer service! They respond every single question that I had.
so far so good By thefish man on 9/24/2018thefish man would recommend this product to a friendThe rock arrived as ordered and had very little damage even though the UPS guy actually wanted to help me open one box do to the fact
that it looked like it went through a hurricane. we opened the box and only found a couple of handfuls of rumble, not bad.
Rest of the rock was nice as expected.
Less weight than ordered and small rocks By Damon on 9/20/2018Damon wouldn't recommend this product to a friendI ordered 30 pounds of rock and only received 29. In addition, about a pound of the rock were useless pieces the size of pebbles. The larger pieces are okay. A 30 pound order got me 4 decent sized flat pieces of rock and a bunch of small rubble. Definitely not happy.
make's aquascaping better By robert on 9/15/2018robert would recommend this product to a friendthis rock is just the best, clean and very elegant. It magnify's the look of my coral and fish. I enjoy the way it fits together and makes for all sorts of interesting shapes and texture.
Good size rock By Roger on 9/11/2018Roger would recommend this product to a friendRock was packaged very good no breakage and I am sure I got more that I ordered.
What is the recommended amount of rock per gallon? I'm aquascaping a JBJ 28 LED tank. thanks!
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!
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!
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.
Is the price shown here the price per pound? Thanks.
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.
How big of rocks can you get I am looking for one rock 50lb or more
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?
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!
If I get 20 pounds of rock, how many pieces of rock would I get?
I would like to order 10 pounds only. Can I specify the size (say around 6 inches) and number of pieces (say 3 pcs) when ordering?
Do the rock come in certain sizes or just random?
There made by nature so they are like snowflakes, each piece is entirely different, though most range in the softball to football size.
What is the weight of one rock?
It will range by size of the pieces however on average a football sized piece will be 5 lbs.
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?
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!
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,
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!
Is the price for the rock for a piece or by pound? If so, how big is the piece?
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!
Do you ship reef saver rocks to Canada? Your website says no tonga, pukari etc.
Yes the reef saver rock can be shipped to Canada.
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?
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?
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.
How many pounds would one softball size be?
Thank you for your question.
A softball sized piece would weight about 2.5-3 lbs. The rock is a natural product so there would be some variation on the size.
Please let us know if you have any questions!
What is the best way to clean reafsaver rocks
Since this rock does not come out of the ocean, there really isn't anything to do but cure it in warm, circulated saltwater and you're good to go. Have a great day!
You mentioned that it is not taken directly from the ocean, may I know that how these rocks are made?
Thank you for reaching out.
The BRS reef saver rock is quarried from fossil coral beds.
Please let us know if you have any other questions.
Have a great day!
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?)
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
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.
Hi, I had about 10 pounds of reef saver rock that I want to add to my 28G tank(some in the sump and some in the display tank) should I cure it? if so, do I do water-changes during?
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?
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 ?
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!
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?
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!
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?
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.
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?
How big is each piece?
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.
Hi I'm setting a 20 gal tank. Please recommend the quantity adequate. Can this be shipped to India??
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!
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
Where does this come from and what's its make up?
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!
Do you have to cure this rock
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?
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.
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??
Hello I have the reef saver rock and wanted to know how many pounds to put in 60 gallon tank ?
About 60lbs total should be great for a tank that size.
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~
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 :-)
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.
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
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.
If I am looking to add more live rock to an already established tank, is it safe to add just 1 rock without curing it to avoid a massive chemistry change, or would I even have to cure a single rock before adding it?
How much does the average reef saver rock weigh?
Whats the average weight per a rock?
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!
Do you need to cure reef saver rock the same as you would live rock or is it fairly free of organics?
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.
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!
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 :-)
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?
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.
Does this rock have to acclamate
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.
