- 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 the pH of your tank 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 tank's 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 and the output side of the reactor. 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 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 tank's 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.

Guaranteed to raise PH By Raphael on 12/15/2018Raphael would recommend this product to a friendI started with ph in 7.8 to 7.9 range on my 150 gallon. After installing this reactor, my ph hovers around 8.15 to 8.2. Media lasts about 10 to 12 days before you begin to notice slowly declining. My recommendation is to attach output hose of reactor directly to the air intake on skimmer pump. Don't install on skimmer silencer, it reduces effectiveness. Also the CO2 media like moist air, so run a hose from the intake of reactor to a section of your sump that will provide humid air. Days to see results depends on size of your tank. For me on a 150 gallon, it took about 4 to 5 days. Cost for CO2 absorbing media will run about $35 per month. Highly recommended!
did the trick By chefmur on 6/5/2018chefmur would recommend this product to a friendstruggled with low PH in my reefer 250 due to new built house. Added the scrubber and within a day PH went from high of 7.8 to 8.2
Easy to install also , highly recommend
Check your air quality first By Nick on 6/2/2018Nick would recommend this product to a friendI had a CO2 problem. This scrubber worked, just barely. If you're serious about solving your PH problem, and you think it's CO2 related, get CO2 monitor. After months of trial and testing different methods, I was ready to give up. I purchased a CO2 monitor, and found that my house was so tight that the levels were 3000 ppm. Accepted levels are 600-1000. Turns out that my ventilation system in my house was not set up correctly. The heater/ac guy who installed the unit, at first gave me that blank look. Turns out that everyone is so concerned with CO, that no one tests for levels of CO2. Know what you're up against, because if your levels are so high, either this scrubber won't work, or, you'll go through media very fast. Just my 2 cents worth.
So far, so good By rtparty on 4/18/2018rtparty would recommend this product to a friendProduct is well built and easy to use. Came with plenty of tubing to connect to my skimmer. I don't monitor pH but know mine stays lower than I'd like since the tank is in a basement and fresh air isn't circulated easily. Just be prepared to replace expensive media every week at the tune of $7 per refill. Mine has run about 10 days and the media is finally around 90% purple. So your mileage will vary.
If BRS's "test" shows that higher pH equals higher growth rates, this may be the simplest and easiest way to increase your pH. It just won't be the cheapest.
CO2 SCRUBBER By Frejr on 4/8/2018Frejr would recommend this product to a friendThis is a great product. super easy to hookup and use.the only down side I see so far is the media. it's expensive.
Instant Results By Ryan on 3/28/2018Ryan would recommend this product to a friendI saw instant results by adding the CO2 scrubber and BRS media to the silencer of my skimmer. I was able to get from 7.8 to 8.04 overnight with zero effort.
Works great By Fred 120G Reef on 3/4/2018Fred 120G Reef would recommend this product to a friendpH was around 7.7 on my reef tank, little too low for my tastes. Got this CO2 scrubber and it worked great. Could see pretty immediate improvement after 1 hour and then over the next 8 hours my pH raised up to 8.1. Can't ask for more. Very easy to install. I have to replace the CO2 media every week for my application.
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.
What is the overall height of this entire unit?
The height of this reactor/scrubber is 14" with the bracket included.
Have a great day!
Can one find the 3/8 tubing on your site for co2 scrubber, sold by the foot
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!
What is the difference between this and the universal air scrubber?
I purchased your co2 scrubber but the tubing is too big for my skimmer. what do I do?
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!
When ordering this product does the internal cartridge can be replace for a clear cartridge or not? A clear cartridge can affect the performance of the absorbing media?
What are the dimensions of the scrubber unit?
This canister is about 12" inches tall and about 5" inches at its widest point. :-)
Do you guys sells just the tubing? I can't seem to find it anywhere on the site.
Is it possible to hook this up to a hob skimmer?
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!
My skimmer is in the back chamber of my AIO tank. Can I mount this under the tank with a longer hose, or will this effect my skimmer's effectiveness?
Have a great weekend!
