Product Questions

Hi, new to saltwater, how do I activate the Dry Live Rock? Will live sand start the process and if so how long should I expect it to take? Also what needs to be done to the dry rock before placing it in the tank. I have a 55 gallon I am converting. Thanks for the time
Question by: Frank R on Oct 25, 2013 11:15:00 AM
Hey Frank,
You got it. Its really as simple as setting up the tank with the rock and just letting it all run a while before you put live stock in. Its hard to say exactly how long it will take, as you want to measure the ammonia in the tank. It will rise slowly over a few weeks and then start to come down, when its 0 is the first point where you can consider adding critters. 4-6 weeks would be a fairly typical ballpark.

Can this rock be used to cycle a new tank?
Question by: Ed on Oct 19, 2013 10:13:00 AM
Hey Ed,
It sure can. In fact thats one of the more preferred ways and its often nice just to do it all in the same tank. Its a lot easier to aquascape dry. We like to do our aquascaping, add our sand, add our water and then let it all cycle.

Hi, is there anyway to request the size? Since i had small nuvo 16 tank. Im afraid it wont fit in my tank if it too big. And how many pounds of live rock do you recommend for 16 gallons tank?
Thank you
Question by: Rudy on Aug 3, 2014 10:42:00 PM
Hi Rudy,
For a tank that size about 15lbs should do the trick. Feel free to put a general request in order comments during checkout. They aren't able to fulfil specific size requests (like 4" x3") but if you tell them you are looking for "softball size rocks", etc that isn't any issue at all.

So is the quantity the number of pounds of rock
Question by: Christian on Aug 28, 2013 2:48:00 PM
Hi Christian,
That is correct. It is sold by the lb, so whatever quantity you enter in the quantity field is the number of pounds you are ordering.

Do i have to cycle my new Fiji rock if have an existing fish reef tank or i can just place it in the tank?????
Question by: Rocky on Feb 13, 2014 4:26:00 PM
Hi Rocky,
You absolutely would want to cycle the rock in a different container before adding to an established tank. Its just not worth the risk of starting a new cycle in something with live stock. You can use something as simple as a bucket or trash can depending on the volume you plan to add.

I'm starting my first saltwater tank, so can I just put this rock right in the tank? Or do I need to do anything with it first before putting it into the main tank? Do I just rinse it off?
Question by: Eric on Dec 26, 2013 3:56:00 AM
Hey Eric,
As long as there isn't any live stock in the tank that is how most of us would do it. Just put the rock in, then put in your sand and your water and let the whole tank cycle together.

I have a 120 gal reef tank that has a load of Aiptasia. I want to replace all the live rock and start fresh.
Is there a way for me to do that without removing the live stock? Or do I break the system down and start
from the beginning? I really don't want to do the later. I have a lot of SPS corals that are OK. What do I do?
Question by: John Zeleniak on Aug 1, 2014 3:56:00 PM
Hi John,
Your situation is particularly difficult. The rock is host to most of the beneficial bacteria that reduce the fish waste. On the one hand it must be replaced slowly in order to allow the filtration to compensate. On the other hand, placing your new rock into a tank with a bunch of aiptasia covered rock is likely just to also become infested with aiptasia. Unfortunetely I think your best bet here really is to break the system down as you don't really want to reuse any water/sand/rock from a tank that is infested or your likely to just spread it right into the new rock.

Full Details

BRS Fiji Dry Rock is the standard rock used in aquariums. Fiji Dry Rock is porous and full of holes that become nice homes and passage ways for your tanks inhabitants. Like all of our dry rock Fiji is 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.


Using Dry Rock has the following advantages:

  • Low initial cost on premium types of rock.
  • Pound for pound a way better value - no water weight.
  • Can be shipped standard UPS ground which saves a fortune on shipping.
  • Absolutely pest free. This is the most important reason. This allows you to completely avoid all of the most common aquarium pests that plague most aquarists.


NOTE: This rock does come out of the ocean and may have some dead material on it such as sponges or other critters. We strongly suggest soaking or curing the rock before use in an active aquarium.

Dry live rock is not available for shipment to Canada due to high tariffs. Please consider Reef Saver rock as it is not subject to these fees and is our favorite of the dry rocks available.

  • BRS Fiji Dry Live Rock By Kyle on 1/20/2016

    Great sizes and shapes to this rock. Shipping was fast and everything was intact and no pieces had been damaged during shipping. Now time to order some more!
  • Great variety, needs cleaning By don_chuwish on 1/18/2016

    Love the variety of shapes and natural artifacts, much more interesting than the 'reef saver' rock. But it is full of dead stuff, dried up sponges, little clams, I even found a dried up hermit crab. I found most of it was easy to remove after soaking for a day. Now it's all curing in a tote.

  • Nice rock By Melody on 3/29/2015

    There look nice in my tank. There was some debris on the rock, and I had to rest it against the glass because the pieces were kinda small. I ordered 40 pounds and was hoping for 1 or 2 large pieces, but I got about 10 medium pieces and a bunch of smaller pieces.
  • Great Rocks! By Colette on 3/18/2015

    I ordered 40 lbs of this. I don't think I could have personally picked out a better box full. Excellent sizes, and I mean big! Very happy with my purchase!!

  • Great quality @ great price By Ray on 2/20/2015

    Great variety of sizes and shapes. Packaged very well - surrounded by a LOT of foam peanuts. Minimal breakage of very small pieces.
