- Universal CO2 Scrubber - Bulk Reef Supply
Carbon Dioxide (CO2) can directly affect the pH of your aquarium, and with a low pH, corals may not grow as fast. Connecting a CO2 scrubber directly to the venturi on your skimmer along with CO2 absorption media you can control the amount of CO2 that is being sucked into your skimmer, effectively raising your tanks pH by removal of excess CO2.
Requires CO2 Absorbent Media (not included)
CO2 is by far the number one cause to low pH in household aquariums. Ambient CO2 can vary from building to building and depending on your location it may not be practical to keep your windows open or pull fresh air from outside into the skimmer. By relocating your protein skimmer's air intake from the silencer over to the CO2 scrubber can actually increase your tanks pH by a couple points. Depending on the amount of ambient CO2 in the room it is not uncommon for tanks to raise from 7.8 pH up to 8.3 pH within a couple days but results can vary.
Connect the included 3/8" tubing to your protein skimmer's air intake. It is usually easiest to remove your skimmer's silencer and directly attach the CO2 Scrubber tubing your pumps venturi.
Unscrew the body from the head of the reactor and remove the refillable cartridge. Add 1 Tbsp of RODI water to the bottom of the reactor body making sure that it does not to touch the CO2 media when the cartridge is replaced. Completely fill the refillable cartridge insert with your preferred CO2 absorbing media and place back into the reactor housing.
Monitor your tanks pH hourly for the first couple days of use. When your pH starts to drop in value (usually 1-2 weeks*) you will need to replace the CO2 media. Most CO2 absorbing media will have a color changing indicator to let you visually see when it is depleted.

Effective By Zotch on 9/22/2017Zotch would recommend this product to a friendPH from Apex and Hannah was 7.8 for months. Set this up before heading into work and monitored via apex. Watched it slowly climb to 8 during the day. Will monitor to see where it levels at and how long the BRS color changing media lasts on my 40 gallon with Aquamaxx HOB 1.5
Love it By Bakerrichard27 on 9/1/2017Bakerrichard27 would recommend this product to a friendPerformance is exactly what I needed ph is a lot more stable now
Works, but with somewhat unexpected negative results By Randall on 8/8/2017Randall wouldn't recommend this product to a friendOK, so this works fine. Fill it with media, plug it into your skimmer inlet (you don't even need an air pump in many cases), and you're scrubbing CO2 out of your incoming air. If you think your pH is too low, this will raise it, at least temporarily. BUT the result is not only that CO2 is scrubbed out of your incoming air, but also that CO2 will be withdrawn from the tank water that comes in contact with that air. And it'll keep pulling CO2 out, resulting in re-equilibration of your buffer system and decreased (potentially plummeting) alkalinity. So kind of a pointless exercise in the end, which is why I stopped using it. There are better (both theoretical and practical) ways to improve your low pH. More water changes and using a doser for 2-part rather than manual dosing come to mind.
Gets the Job Done By Andrew on 7/27/2017Andrew would recommend this product to a friendI've had this product for over 3 months. Prior to install my pH was consistently around 7.9. After install my pH has not dipped lower than 8.2. If you have problems with stabilizing your pH and are on the fence about whether or not to get this product, do it and thank yourself later.
Great product By Ace87 on 7/9/2017Ace87 would recommend this product to a friendI am happy with the quality of the product. Disappointed because I only get 24 hours out of the media before it is spent.
Does a nice job By Nick on 5/28/2017Nick would recommend this product to a friendHad a problem with my new tank. The PH was at 7.6 during the day and dropping to 7.5 at night. I had tried Kalc. That would raise the PH but then the next day it would return to 7.6. I was about to reach the thought that I just couldn't have a tank. Until I tried this scrubber. Now, with this running, I was able to get it to 8.0. Now adding Kalc I'm at 8.20 and steady. I never thought excessive CO2 was my problem but I was wrong. Glad I tried this scrubber.
Wow By Michael on 5/5/2017Michael would recommend this product to a friendAll I can say is wow!!! I hooked up the scrubber this morning, ran some errands and came back to a pH of 8.28 and was down this morning at 8.12. Corals look bigger and fluffier. I hope it also helps with taking out the cyanobacteria I have a problem with at the moment. We'll see and keep you updated. Great so far for 8 hours of work!
WOW! By bavass on 4/4/2017bavass would recommend this product to a friendvery easy set up, PH went up and what surprised me was the added benefit that my skimmer is performing better to!
Co2 By Midtownman on 3/15/2017Midtownman would recommend this product to a friendMy ph would fluctuate between 7.6 to 8.0 since then I installed the c02 scrubber to my skimmer and my ph is at 8.3 my coral looks fuller and happy and I had it on for three weeks and the bottom and barely changing color
Excellent product By HG on 2/23/2017HG would recommend this product to a friendUsed the BRS CO2 scrubber with the BRS soda lime. PH went from 8.01-8.29 within a couple hours and has remained stable for the past couple weeks since setting up. Soda lime still going strong with no signs of exhaustion
Great! By SteelPenguin on 2/16/2017SteelPenguin would recommend this product to a friendI did not like constantly adding buffer to try and maintain PH. I finally got tired of the swing cycle, and decided to try a CO2 scrubber. I like the way this unit is tightly sealed so that all of the air passes through it before reaching my skimmer intake. I had a really difficult time raising and maintaining my PH above 7.9 to 8.0. Literally, as soon as I hooked this unit up, it started climbing. My tank is now at 8.22 PH with virtually zero effort on my part. I have only filled the unit once, and I tried the Two Little Fishies branded CDX, so far (3 days) no color change. I also purchased the BRS branded media...I will try it on the next fill.
Satisfied By Corey on 1/27/2017Corey would recommend this product to a friendI've ordered 2 of these now. Both working well but for some reason the 2nd one came with a larger size tubing/slip adapter than the 1st one did. I managed to make it work with a Tunze 9001 but needed to buy some smaller tubing.
Today we're answering James Sparkman's question: " ...

The height of this reactor/scrubber is 14" with the bracket included.
Have a great day!
We are currently working on getting this up on the website to support our scrubbers and other products. You should be able to purchase it on the website soon!
Have a great day!
If you need a different size barb for your skimmer hose, we do sell various adapters located on this page https://www.bulkreefsupply.com/ozone-resistant-kynar-elbow-male-npt-x-barb.html which should fit your needs.
Have a great day!
This canister is about 12" inches tall and about 5" inches at its widest point. :-)
You can hook this unit up to any skimmer but I would be aware of the possibility that the skimmer could back-siphon and cause a spill. If possible i would mount this at or above the height of the skimmer to eliminate the possibility.
I hope this helps!
Have a great weekend!
