Works exactly as you would expect, removing CO2 which increases your PH (at least it did that for me). I only wish the color change would last longer and not go from white to purple (lavender?) back to white. Of course when you test and your PH starts to go down you know its time to replace.

This product has not only help cut down the CO2 but has kept my PH at 8.0- 8.2. Before my Ph would go from 7.6 - 8.0 through out the day while ALk levels was as high as 11. Now I can kepep the ALK at 9 /10 with the Ph stable.
Does help with PH. By Franklyn on 12/17/2014

The product does what it advertises, the only complaint I have is that it exhaust quicker than advertise. I normally have to replace the media every 2 weeks. With that said, this is been the only way I have been able to stabilize my PH. Before the CO2 scrubber my PH would drop below 7.8 and now Im able to maintain it at around 8.0

I was having issues with my PH being to low. I did some research to correct it and found that the CO2 levels where affecting my PH. If I had friends over I would see a rapid drop in my tanks PH. We do not open the doors or windows much as it is very hot in Florida. I first tried a different brand to see if a CO2 scrubber would work which it did. When I discovered BRS and there CO2 media I tried it and am very happy with the results. It works and stabilizes my PH using a reactor connected to my skimmer air intake.
ND Winter = Low pH By Jordan on 4/29/2014

I love this stuff. I am not really able to open up windows for 3+ months/year due to North Dakota's crazy winters. This keeps my pH between 8.1 and 8.4 consistently. I run it in a BRS reactor.
Works but at a price By Brennen on 3/26/2014

This stuff does what it says. I noticed a change right away, ph stayed higher at night with less swings. I live in an apartment with a lot of trapped co2. The major con is that the media does not last long. I have been running a canister on my reef octopus skimmer for about 5 days now and its nearly exhausted and ph is back down to were it was. So I don't know if I would consider this a fix for the problem. If you can, run your skimmer line outside for fresh oxygen.

I had been having ph problems for months and could not open all of the windows in my house year-round nor could I justifiably run an airline from my tank to the outdoors. To solve the problem I bought the BRS Universal Air Filter along with this CO2 Absorbent. Both have been working great and ph has come up. Before running the air filter on my skimmer air intake my ph was 7.4-7.6 day and night. Now after running this for only a few days my ph has been steady at 7.7-7.8 and occasionally peaks at 7.9 at the tail end of the day.
The media is being used up quite quickly but I'm assuming that is because I have a rather high CO2 concentration in my home. This is definitely a good product that I would recommend to anyone with low ph issues related to CO2 levels.
Low pH got you down? By Tommy Gee on 12/30/2013
Tommy Gee would recommend this product to a friend
Many of us reefers cannot be satisfied if any of the parameters of our tank fall outside of what is considered to be the 'acceptable norm.'
Only after countless attempts to improve what I felt was too low of pH range (e.g. 7.78 to 7.9X) did I discover a few things about pH.
After reading several articles, I came across one written by Randy Holmes-Farley. Only after reading two publications on pH and Alkalinity did I understand how to better manage pH.
What did I discover? It was the concentration of CO2 in the air that was depressing the pH in my mixed reef! But how could I overcome the air (concentrations) within my home?
1.) Open the windows. Nope. I live in Florida where it is warm-hot much of the year.
2.) Run a feeding line through the wall to the outside to draw fresh air to my tank. Nope. This one doesn't pass the "wife-test."
3.) Utilize a CO2 scrubber. Yes!
Soon after I received my BRS Media Reactor and CO2 color changing Media did I see an improvement in pH.
Installation of the Reactor (and the Media) was a snap.
The BRS Reactor comes with quality airline tubing and a media container. Just add the color changing media to the container, then add one teaspoon of RO water to the cylinder, then drop the container into the Reactor.
Now connect the Reactor to your skimmer. The airline feeding my skimmer was connected to the OUT line of the reactor. I used the provided quality tubing provided to make this connection. In this configuration, the Reactor pulls in air from the room, scrubs it, then delivers it to the skimmer ('scrubbed' of excess CO2).
How much of an improvement was achieved? Well prior to the installation, the pH (on the low side) was 7.6X, with higher side at 7.8X.
With the scrubber operational, I noticed about a .15 to .20 increase in pH. Now the pH (on the low side) was 7.8X, with the higher reading (after the midday lighting was achieved) of 8.0X. Success!
Am I satisfied? Yes. By the way, I have been using this product now for 10 months with good results.
Does what is says By Christopher on 11/12/2013

This another great product from BRS. it solves what most of us experience and that is low PH. my PH was running between 7.7 and 8.0. Using this product I am able to maintain a more stable PH between 7.9 and 8.3. The downfall of course is price and the longevity of the media will depend on how much CO2 is in your house so results will vary by user. In the mean time this will work for me but in the future I think I will try an air line from the outdoors to my skimmer. I think I will be able to maintain the same results. Another great product from BRS!!!

I couldn't get the PH of my tank out of the 7.7-7.8 range. For 8 months of the year between the AC and the heat, the house is pretty much sealed tight with windows and doors closed. Tank is in a position where running an airline from my skimmer to the outside was not an option. Started using the CO2 absorbent and within 24 hrs. PH went from 7.87 to 8.15
CO2 getting you (and your pH) down? By TommyGee on 6/9/2013
TommyGee would recommend this product to a friend
For the longest time, I could not properly assess why the pH in my reef system continually ran in the 7.7X range despite my best efforts to elevate it.
After review of numerous articles, I finally came across one by Randy Homles-Farley that spoke to directly to my issue i.e. excess CO2.
I wouldn't have thought the "green" energy efficient new home I was living in could be a contributing factor....but when you step back and assess why it's energy efficient it makes sense i.e. there is no interior to exterior leakage i.e. air-exchange. That means when the AC is on, we are only cooling the interior of our home and not leaking cool air outside.
Having said that, I noticed an improvement in pH the day I installed the BRS Media Reactor + Color Changing Media. The pH that consistently ran in the low 7.7X range now hovered in the 7.9X+ range througout the day. Also, the color changing media (from white to purple) makes it easy to detect when the media is exhausted thereby assisting in the visual (non probe/test kit measurement) management of pH.
If you are looking for an easy to install/use tool to assist in pH management, you've found it. I highly recommend this product.

I got new windows and insulation in my house. Could not keep my ph above 8. Put this stuff in a geo reactor I wasnt' using and ran a line to my skimmer intake. My ph literally went from 7.8 to 8.2 in four hours and this was after I installed at 11 o'clock at night. Now just to see how long it actually last.

Used with Universal Air Filter . Had low PH in tank due to elevated CO2 in house. Hooked it up to skimmer and PH is already coming up.

Product does work but does not last long . Lasted 2 days before turned purple and Ph dropped back down. Save your money just run air line to outside of house if interior CO2 levels to high.

i was one of those reefers where all my levels were spot on & my low PH was the missing link... some of my corals just weren't thriving as they should... I tried KALK but it threw my ALK over 12 & the PH only stayed high for a short time & then dropped off... i was skeptical that this filter would even work... it took 4 days, but this morning to my surprise, my PH bottomed out at a record high 8.08 & its midday & my PH is at 8.20 ... my PH used to bottom out around 7.8 & only get as high as 8.05 unless i dosed it. i am seeing close to a .4 swing with this filter... that's HUGE! I guess i had a CO2 problem after all... This filter is great!!! It change my whole outlook on the corals I can put in my tank... Only downside, the media is expensive & in the 1st 4 days of use, 20% of the media chamber turned purple... lets see how long the 9lb jug lasts me...

Product works as it says. You will need to purchase the Universal Air Filter as well. I would also highly recommend a PH monitor if you already don't have one. An American Marine Pinpoint PH monitor works perfect. I now have more control over my PH than I ever have before. Thanks BRS.

This stuff is amazing. Since turning the heat on I've been having low Ph 7.6-8.0. I got the CO2 absorbent, made my own reactor with parts here on BRS, and withing 48 hours my Ph was stable at 8.1-8.4. Aweseom stuff. I have been running it for 2 weeks no, and not sigifigant color change, so it should last a while inbetween changes.

Every winter I fight low pH. It’s a continuing battle of trying to keep my pH from falling to low while trying to not drive my CA and ALK through the roof.
My pH was running around 7.68 in with my CA and ALK max out. Three day after installing a skimmer air supply scrubber with this CO2 absorbent my pH has been running a solid 8.25 to 8.38. I wish had found it a couple of years ago. No more fights with the wife about opening a window for better air and in the process heating the front yard. This stuff is outstanding!
