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.

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.
