ROX 0.8 - Our Best Aquarium Carbon
- Removes Yellowing Pigments, Contaminants, and Odor
- Use in a Media Bag or Media Reactor
- Very Low Dust - Minimal Rinsing Required
- Use Half the Amount vs Standard Carbons
For those seeking top-notch filtration performance, Bulk Reef Supply ROX 0.8 Carbon is the go-to filtration media. Despite a slightly higher upfront cost, ROX 0.8 Carbon proves cost-effective as about half the amount of this carbon is needed to achieve the same results as standard carbons commonly found in the aquarium hobby.
Known for its excellent adsorption properties, ROX 0.8 is capable of removing a wide array of contaminants, yellowing pigments, and irritants from aquarium water. This specialty carbon is extruded into tiny, extremely hard pellets, which results in less dust and reduces the amount of rinsing necessary before use. It features a high number of large and small pores, giving it the advantages of both lignite and bituminous carbons.
Why Should I Use Carbon in My Aquarium?
Carbon has many benefits in an aquarium, including:
- Odor Reduction: Keeps your aquarium from smelling fishy.
- Improved Water Clarity: Achieves crystal clear water by removing yellowing pigments.
- Toxin Removal: Effectively adsorbs toxins and other harmful chemicals from the water.
How Often Should I Change Carbon Media?
While frequency of changing will depend on your aquarium bioload and other factors, a good rule of thumb is to replace the carbon media in your aquarium every 2-4 weeks to ensure that it remains effective.
Recommended Dosage: 1 tablespoon per 10 gallons or use our Reef Calculator for hassle-free dosage recommendations.

Product Questions
Can I put this in a normal filter bag or does this have to be in a reactor? If so, does the same amount recommendation apply? So for a 90 gal with a 30 gal sump would be 11 tablespoons per filter bag? Also, I don't run GFO but do run biopellets. Is this ok?
Question by: Cass on Dec 15, 2023, 7:40 AM
Hey there, You can use that in a reactor or a filter bag. And we have a calculator you can use here https://www.bulkreefsupply.com/reef-calculator/carbon-calculator-aquarium and yes using bio pellets is fine as well. Thanks!

I've read that it matters how carbon is activated as to whether it leaches phosphates. Is this carbon activated chemically or physically?
Question by: Laura M on Mar 7, 2018, 5:18 PM
Hi there,
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 micron filter bag is needed for rox0.8
Question by: Jeff on Jan 18, 2018, 7:15 PM
We suggest a media bad that has a micron rating of 300 or lower. That will contain the media within the bag and still allow for good water flow through the bag.

how much should i use for 45 gallon freshwater?
Question by: Mian Ali on Nov 19, 2017, 1:30 AM
I'm afraid we only normally work with saltwater applications, and wouldn't have info for freshwater use, but our normal recommendation would be about 4 Tbsp for a 45 tank.

As far as concern over dust relative to risk for tangs/HLLE, is Rox the best reef carbon available?
Question by: Cheree on Nov 19, 2017, 1:23 AM
While I've not seen any research showing any difference between different carbons and their effect on HLLE, Rox .8 is definitely the highest grade of carbon available and has the lowest dust level.

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?
Question by: Jose on May 17, 2016, 9:53 AM
Great question!
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.

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?
Question by: Matt on Feb 2, 2016, 5:20 PM
Great question!
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!

What should the rate of flow be in a reactor with carbon? Enough to barely tumble, no tumble, or other?
Question by: Kyle C on Jan 26, 2016, 5:44 PM
Greta question!
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!

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?
Thanks,
David
Thanks,
David
Question by: David on Apr 4, 2014, 6:01 PM
Hey David,
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.

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!!
Question by: Robert on Feb 28, 2014, 5:15 PM
Hey Robert,
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:

How long will the media brs GFO high capacity & Premium POX 0.8 carbon be changed?
Question by: wing on Jan 20, 2014, 9:17 AM
Its best to change carbon every two weeks. GFO on the other hand will vary depending on the amount of phosphates in the water. No need to change it until its depleted. Typically this is 4-6 weeks assuming normal dosages and normal phosphate levels but the best thing to do is monitor your phosphates for an increase, and change the GFO when the phosphates begin to rise.

What kind of carbon is recommended to run in a reactor
Question by: Rick on Oct 28, 2013, 11:56 AM
Hey Rick,
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.
