It is recommended to perform a large water change or series of changes to remove nearly 100% of the water. The reason being is to remove nutrients before starting the cycle. Feel free to let us know if you have any further questions!
This rock is man made and hand painted to replicate coraline growth. The rock will still need to be cured however to ensure that the nitrifiying bacteria has time to appear on the rock. If placed directly into a system there is potential for algae growth on the rock if lights are on and a pH swing may occur.
This is essentially man made concrete rocks which are painted over. There certainly will not all be 100% purple covered however in our experience we have found this to be a great rock to aquascape with, and after a few months in the tank the rock is very natural! The same experience can be had with many other types of natural dry rock. Feel free to let us know if you have any further questions!
We highly recommend keeping all lights off and the tank in a dark room with limited light penetration to reduce any possible algae growth which may occur with the excess nutrients. Feel free to let us know if you have any further questions!
Unfortunately we are unable to split up the packages on the project reef rock. At this point a rock such as reef saver sold by the pound may be a better option! Feel free to let us know if you have any further questions!
Your site states that it is covered with a thick purple paint - is that correct?
Is the rock solid purple through and through?
The 55lb box will not have larger pieces rather the same size but larger quantity. Overall the average size will be around a football. Feel free to let us know if you have any further questions!
ReefRock 2.1 is a dry rock that should be cured before use.
As with all of the ReefRock products the rocks colors will vary from Coraline pink to deep purple.
Available in 3 different volumes:
11lb - Great for pico and nano tanks. Rock sizes can vary from small baseballs to small footballs
22lb - Great for nano tanks. Rock sizes can vary from small baseballs to large footballs
55lb - Great for nano and larger tanks. Rock sizes can vary from small baseballs to small soccer balls
Reef Rock 2.1 is manufactured by mixing reef substrate, that is a mixture of sand, coral pieces, shells and more, with a cement mixture allowing natural textures and shapes to be created. The reef substrate mixture allows the rock to have a porous network within the rock giving it many of the natural characteristics of rock straight out of the ocean.
After the rock is hand made it is then cured for 6 or more weeks allowing the cement and reef substrate mixture to fully harden and neutralize before it has a thick coating of purple, reef safe, paint applied around the entire exterior of each rock.
BRS recommends 1 pound of rock per 1 gallon of display tank volume for the average aquascape. Depending on the tank you may like more rock or less rock, however we would always recommend ordering a few more pounds of rock than you may need, as any extra rock can always go into your sump for added filtration.
With each rock being hand made, a variety of rock will be in every box. We are unable to guarantee any specific sizes or shapes.
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.
Leeches phosphates By Reefahholic on 4/8/2017Reefahholic wouldn't recommend this product to a friendDon't buy it. It looks great, but leeches PO4. It does flake and pieces of the rock float around the tank. My PO4 has consistently been over 200ppb with Hanna ULR. Check out my YouTube video about it. https://www.youtube.com/watch?v=53lHr8_wBI4&feature=share
Not what you think it is By con on 2/28/2017con wouldn't recommend this product to a friendFirst off his rock is not porous at all I read all the reviews on here and thought I'd give it a shot. But I ended up being very unhappy with my purchase. I'm constantly fighting bacteria blooms on these rocks I heard its supposed to be hard for algae to grow on them because of the purple coating but that's not true. Not only does it grow algae on it but the purple coating peals off in a couple of after first introducing it to the tank. This rock is just OVER PRICED CONCRETE don't waist your money on it.
Great looking rock that is easy to aquascape with By rsepiphyte on 2/18/2017rsepiphyte would recommend this product to a friendThis rock look naturalistic and is very easy to work with. I have been using the Zeovit system with it along with marine pure and have not had any algae outbreaks or other problems with you. Love this stuff!
A+ By Daniel on 1/26/2017Daniel would recommend this product to a friendI read all the reviews before I bought this. I have to say most of them are right.. There are two different colors of rock.. Some of the paint chips off, not much and I "cured" mine in heated circulating water for a couple weeks and most happened in there.. I had a couple broken pieces, easy to fix..
But that being said, with a little work and preparation it looks great in the tank.. No pests.. aquascapes very nicely... No phosphates leaching..
Inconsistent quality and color By AAnative on 1/17/2017AAnative wouldn't recommend this product to a friendPurchased two boxes of this rock (22 lbs each) and the two boxes are completely different colors and textures. One box is light purple and rough textured, the other box is extremely dark maroon-brownish. The second box is very smooth as the coating of paint seems to be much thicker. BRS gave me a hard time when trying to return one box. This is a "non returnable" item for some reason. I had to pay return shipping. Advice - buy the largest box they offer so your rocks look the same.
Looks good out of the box By Jimmy on 1/15/2017Jimmy would recommend this product to a friendI ordered 55 pounds for my 120, partly based on how well I like the overall effect created by the rock in the BRS 160 gallon tank featured in the "52 weeks" videos. I am going for a more minimalist look for this new tank, but I believe I will need to order another 22 lbs for my 120 gallon tank. I was satisfied with the condition of the rock when it arrived, and impressed by how easy it is to work with in terms of stacking and creating organic, natural-looking shapes. Yes, a couple of pieces had broken in half during transport, but that was easily remedied with the BRS gel CA. There were also several "dings" on the rock where the greyish concrete shows through, but this is barely noticeable when the rock is wet. Also, I haven't noticed any paint flaking as pointed out by other reviewers, but again, my rock is not not yet in water. So far, I am very pleased with this purchase!
flaking after 1 month By burt again on 1/5/2017burt again wouldn't recommend this product to a friendUnhappy to report that are are some negatives. Stories of the rock flaking purple paint are true. Not good.
no negatives By Burt on 12/31/2016Burt would recommend this product to a friendsoaked in RO/DI for 2 weeks then cycled a tank with it...what small flaked fell off fell off in the RO/DI container, that was it...the rock did not leak phosphates. no pieces were broken. paint did not flake. It is not fake looking. it stacks brilliantly, looks great in the tank. combined with a block of marinepure you can't go wrong, IMO.
Great Product By Jen on 11/2/2016Jen would recommend this product to a friendI just came back to reefing after 10 years away. I set up my 60 cube with 55 # of it. I love how the rock fit together and looked natural from day one. My tank has gone through the normal new tank cycles, but nothing terrible. I could not be happier with the quality and appearance. I will not know how it does long term for awhile, but at this point I love it.
3rd Time Isn't a Charm By Chris on 9/25/2016Chris wouldn't recommend this product to a friendThis is the third time I have ordered this rock, with the first 2 I was happy with what I received and used in the setup. This time however there was a real drop in quality. Evidently nylon strand similar to fishing line is used in the making of the rock inside of the mix. On about half of the pieces, there were sections of 1-3" sticking out obviously from the rockwork and paint causing a real eyesore and more work for me having to dig and cut it out. Also the variation in the shapes has seemed to drop. Had I not already had about half of the rock in the running tank been this type, I probably would have started over with something else. Disappointing.
I'm actually pretty upset. By Niko on 3/26/2016Niko wouldn't recommend this product to a friendI gave this rock a chance after reading a bit about it on here. Fast forward a few months and I have to say I am pretty upset. I've had constant bacteria blooms. At my loval meeting I asked a few other people that I know have it and they experienced the same thing until they took it out. This rock is not porous and you will regret buying it in the future. I don't even know if BRS even reads these reviews, but if I was them I'd take this "rock" off the shelves. All that money wasted for no reason, should have stuck with my own opinion on it.
Good rock By Arnie on 3/24/2016Arnie would recommend this product to a friendI have had this rock in my tank for the last 6 months or so. Great appearance and rocks are quite algae free which indicates that they are not leaching any posphates or other nutrients into the tank.
Quite happy with them so far.
