- BRS Bulk Premium ROX 0.8 Aquarium Carbon
Why does BRS recommend this?
When it comes to filter carbon we are pretty picky and wouldn’t recommend any ordinary carbon. The ROX carbon in our opinion is the best carbon on the market, only requiring half as much as most standard carbons. It may cost a little more upfront, however being able to use less and see faster and better results more thanmakes up for this. Also, with its super low dust content, rinsing is quick and doesn’t require much water at all.
BRS Bulk Premium ROX 0.8 Aquarium Carbon offers superior absorption, less dust, and pristine water clarity. Typically used by pharmaceutical companies to create ultra-pure water. The wide variety of pore sizes makes it the best aquarium carbon available to remove yellowing pigments, contaminants and irritants from your tank.

ROX 0.8 is a specialty carbon extruded into tiny, extremely hard pellets resulting in less dust and reducing the amount of fines released into the water. It features high numbers of large and small pores giving it all the advantages of both lignite and bituminous carbons. ROX 0.8 will make your water crystal clear faster with less material.
BRS purchases our carbon directly from the manufacturer so we can offer the best carbon at reasonable prices. While most companies claim their carbon is the best, our statement is backed with true science and real numbers. Carbon is not created equal. Different sizes, shapes, and materials will perform with drastically varying results.
Recommended Dosage: 1 tablespoon per 10 gallons, or use our Reef Calculator for hassle-free dosage recommendations.

Best carbon hands down By Alfredo De La Fe on 5/8/2020Alfredo De La Fe would recommend this product to a friendThis is the cleanest, highest quality carbon I have ever used. Works as advertised. Be sure to use a media bag, the grains are on the small side but the results are well worth the additional caution.
Makes a mess By Bruce on 4/22/2020Bruce wouldn't recommend this product to a friendI placed it into my reactor but the particle size is so small it passed through the sponges and FLEW into the water column. What a mess. Never again. Will just throw this in the garbage.
Love this stuff! By TJ on 2/23/2020TJ would recommend this product to a friendUse only Rox, change in every 2 months in a non stocked aquarium. It runs clean almost instantly. Very easy to use. I only use this and will never switch back to anything else. Great job guys, love all BRS products.
Best $ spent By Cassandra on 2/15/2020Cassandra would recommend this product to a friendPerfect size and practically washes clear.
Great stuff By Larry on 1/23/2020Larry would recommend this product to a friendI use it in both my freshwater tanks and i love it. Water seems cleaner within hours . YOU HAVE TO USE A FINE MESH SOCK OR BAG OR DONT BOTHER USING IT. its great
ROX 0.8 By Reef Tank Guy on 7/15/2019Reef Tank Guy would recommend this product to a friendPristine water everytime. Very clean.
I HATE THIS PRODUCT By matthew / A Reef Insanity on 5/20/2019matthew / A Reef Insanity wouldn't recommend this product to a friendI have used this and the other grade both by BRS and both are not affective for large fragging systems or large displays. I am not sure it would even do well in any sized tank. I will stick to a much cheaper brand that works wonders and I get 5x as much for the same price. Overall; other than the BRS Reactors the media by them are WAY OVER RATED.
Great Carbon, a little goes a long way! By Michael on 4/6/2019Michael would recommend this product to a friend100% would recommend! Water seems to clear up in hours. I use ROX 0.8 and Red Sea carbon, and I haven't regretted either. ROX seems to absorb so much more than any other carbon, so you only need half as much to get the same job done.
Only Carbon I Will Ever Use By ChiclidMan on 11/26/2018ChiclidMan would recommend this product to a friendI have a 125 gallon aquarium fill with Malawi Chiclids. This carbon is amazing. Use only one tablespoon per 10 gallons. It keeps my tank water crystal clear. The water has NO oder whatsoever. I don't even think I need to rinse the carbon before using it.
Works Great By John on 11/3/2018John would recommend this product to a friendWorks great. I have a tang and he is perfectly healthy. No lateral line issues at all.
Works well By Rick on 10/14/2018Rick would recommend this product to a friendWorks very good
Great By Andy on 8/9/2018Andy would recommend this product to a friendAwesome. Using in m BRS dual reactor. No problems. Keeps tank crystal clear.
How much carbon should I use? What's the carbon to gallon ratio for this carbon? Planning on putting it my my BRS dual reactor. Thanks!!
With the ROX carbon it comes out to 1 tablespoon per 10g of water. Or if you want to do the math the easy way, use the reef calculator found at this link:
I've read that it matters how carbon is activated as to whether it leaches phosphates. Is this carbon activated chemically or physically?
Thank you for reaching out.
Our ROX carbon is steam activated and acid washed with hydrochloric acid and not phosphoric acid so there is no danger of it leaching phosphates into the water.
Please let us know if you have any other questions.
Have a great day!
What should the rate of flow be in a reactor with carbon? Enough to barely tumble, no tumble, or other?
The flow rate will vary however the flow is often around 300 GPH. The Carbon should be held in place with sponges and should not be allowed to tumble. Feel free to let us know if you have any further questions!
Will this work for freshwater? I'm sure it will because it's just crabon but I need to make sure.
This will work perfect for freshwater! Feel free to let us know if you have any further questions!
As far as concern over dust relative to risk for tangs/HLLE, is Rox the best reef carbon available?
Have a great day!
How much should i use for 45 gallon freshwater?
Have a great day!
What micron filter bag is needed for rox0.8
What does Rox.8 remove from the water? Thank you in advance

I just got an old Red Sea Max 250 set up and running which is 65 gallons. I have a c-220 canister filter on it that normally takes 2-100gram carbon bags or just over 13 tablespoons. I see this carbon only recommends using 6.5 tablespoons for my size aquarium. Is it really that good that I can use half the amount as other brands?
Correct, the ROX 0.8 does have twice the performance as the standard Bituminous carbon used in many other aquarium products. Feel free to let us know if you have any further questions!
Can I run GFO and ROX Carbon in one delux reactor and biopellets in another seperate reactor? Or is it advised to only run one phosphate removing media at a time?
We do not recommend running bio pellets in conjunction for tow reasons. The pellets will clog and release waste film which will clog the system in addition of GFO not needing to be run with pellets as the pellets do require a small amount of phosphate to perform correctly.
How long will the media brs GFO high capacity & Premium POX 0.8 carbon be changed?
Do you know how many cups of ROX 0.8 are in the 1/4 gallon container?
There will be 4 cups per 1/4 gallon.
Which reactor do you recommend for the ROX 0.8 carbon? Do you have one that will compress it and keep it between filter pads where it can't escape to the tank?
The standard BRS reactor I think is the best for the ROX carbon. Its filter pads are fine enough that the carbon stays inside of them. There are a lot of great reactors out there, but with most of the other ones you will need to custom cut some filter floss material to keep the carbon from going through the sponges as its quite small.
What kind of carbon is recommended to run in a reactor
It really depends on the reactor. The ROX carbon is the best carbon we sell, but because of its small particle size its well suited to reactors whose sponges have large holes in them. For those types of reactors the lignite carbon will be the best bet as its still performs better then most carbons while being a larger particle size.
