Does help with PH. By Franklyn on 12/17/2014Franklyn would recommend this product to a friendThe 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
Works Great By Pat on 5/18/2014Pat would recommend this product to a friendI 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 4/29/2014Jordan would recommend this product to a friendI 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 3/26/2014Brennen would recommend this product to a friendThis 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.
Great Product By Anne on 12/30/2013Anne would recommend this product to a friendI 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 12/30/2013Tommy Gee would recommend this product to a friendMany 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 11/12/2013Christopher would recommend this product to a friendThis 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!!!
Great product, works well! By kevin on 9/3/2013kevin would recommend this product to a friendBought this to raise my pH levels. Raised my pH level 3 points in 24 hours. Clean and dust-free.
Great product By Melvin on 8/19/2013Melvin would recommend this product to a friendI had a low PH problem and this was the cure for it. Works as stated can not live with out it.
Does the Job By Den on 8/17/2013Den would recommend this product to a friendI 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 6/9/2013TommyGee would recommend this product to a friendFor 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.
Wow By Mike on 3/21/2013Mike would recommend this product to a friendI 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.

I currently go though alot (1 canister for 60G of water) of DI resin and I beleve it is the CO2 hght amout of CO2 in my well water
Would this product help in using reducing the COI in my RO water if I put this in a filter before going into my DI?
Bulk Reef Supply Hey Christian,
The co2 absorbent unfortunately is only for removing CO2 from air. It can't be used to remove the CO2 from your water unfortunately.
by Edwin on January 19, 2014, @1:36 PM
Can I use this co2 absorbent in a two little fishes rector because I'm currently using the cdx media but would like to try this one but I see you have to add a little RO water in the canister but I can't do that on my current reactor
Bulk Reef Supply Hey Edwin,
That would work just fine. All you need to do is put a few drops in the bottom of the phosban reactor when you change the media, its not something that needs to be continually done :-)
by JnSrh8084 on May 15, 2014, @4:46 PM
What canister is needed for this? Does it come with one? Can you use this in a phosban reactor that is simply setup in a sump using a pump and returns back into the sump? What kind of flow rate is suggested for best results slow or fast? I seen people hooking this up to the air intake of a skimmer, is that a more correct way to use this or will I have the same results using a phosban reactor and at x flow rate? Sorry for all the questions but they haven't seemed to be addressed yet! Thanks in advance!
Bulk Reef Supply Hi there,
The CO2 absorbent material is for filtering air, generally run inline before your protein skimmer. You wouldn't want to get it wet so no worries about flow rate :-) You could use something like our universal air filter or it is possible to use the phosban reactor with the CDX adapter, which converts the phosban fittings to a barb for easier connection to a skimmer.
BRS medical grade soda lime has the following features not available in standard soda lime.
- Contains a special Zeolite to reduce the risk of drying out which results in in the media lasting longer.
- Uniform shape allows consistent bed packing, resulting in a more even flow through the cartridge and longer life span.
- The unique manufacturing process used to produce our product ensures that the dust content of the product is significantly lower than other soda limes
Soda lime is commonly used in the aquarium industry to remove carbon dioxide (CO2) from the air before it is injected into a protein skimmer. This will raise the pH of your tank and help you reach or get closer to the 8.3 everyone desires. Soda lime is particularly helpful if you are running a calcium reactor or live in a tightly sealed house. This is pretty much the only way to continually maintain an elevated pH without effecting calcium and alkalinity levels.
Instructions for use.
1) Fill cartridge with soda lime
2) Add one teaspoon of water to the bottom of the filter canister (not the cartridge). Do not get the soda lime wet.
3) Connect to the air intake of your skimmer.
4) Replace media when it turns purple or PH of the tank begins to drop. Please note that the color change is gradual and the media will get darker over time as it is depleted.
