Product Questions

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
Question by: Edwin on Jan 19, 2014 1:36:00 PM
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 :-)
Answer by: Bulk Reef Supply on Jan 19, 2014 1:36:00 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!
Question by: JnSrh8084 on May 15, 2014 4:46:00 PM
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.

Can you explain the necessity of placing a small amount of water at the bottom of the canister? What does this do? What happens if you do not? How often should you check it to see if it has evaporated?
Question by: StumpytheParakeet on Apr 28, 2016 8:48:00 PM
Great question!
The small amount of water is to ensure the humidity levels are appropriate for the media to absorb CO2. The media should not come in contact with the water. Without the water the media will have a tougher time absorbing excess CO2. Weekly checks to ensure the evaporation levels are required.

How long does this media typically last? I have a 150 gallon reef tank. I just want to know if I should expect to replace it every week or every couple of months just want to get an idea.
Question by: gil on Jun 11, 2016 8:39:00 PM
Great question!
This will typically last in the 2 week range however the color will change notifying when it is needed to be changed. Feel free to let us know if you have any further questions!

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?
Question by: Christiaan on Sep 1, 2013 7:52:00 PM
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.

Full Details

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.

  • Excellent By jordan on 4/14/2016

    If you have low PH issues this is your easiest fix. I hooked mine up to my skimmer and converted a BRS GFO/carbon reactor to put the media in and works like a charm. Before my PH peaked at 8 and the low point at 7.7. Now with the media it peaks at 8.3 and the low point is 8.1.
  • Product Works as Advertised By Rick on 3/28/2016

    Hooked it to my skimmer air intake using reactor...pH increased in about 48 hours from 8.0 to 8.22 and held constant
  • Works great By Mark on 3/10/2016

    Product works great only draw back is I have to change it every week
  • Didn't work for me By Jeffrey on 2/20/2016

    I run this through a BRS reactor to a Vortex Omega 150 protein skimmer. I run my 120 gallon tank with an Apex Fusion controller with lab grade probes. There Apex shows no difference in pH with this product. Maybe it would work on a smaller tank.
  • Works well and color change By Polymorphyc@gmail.com on 2/6/2016

    The product works well in the appropriate reactor. Does exactly what it describes. I like the color change option, no guessing when it's been consumed.
  • Not really sure By Justin on 1/1/2016

    Have used this product for a few weeks so far hasn't raised my ph at all. Not sure how much to use since I have a big tank (300 gallons) I filled the reactor full and has already turned purple. So I changed it out. But at this rate it will cost me 50$ a month and let it still hasn't raised my ph.
  • Stability By Ol Crusty on 12/20/2015

    This does what its supposed to do removes co2 it keeps your ph higher and more stable.
  • Great! By Artem on 11/3/2015

    It works!
  • It's great By Steven on 9/17/2015

    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.
  • The Best By DAVID on 9/10/2015

    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
  • Works Great By Pat on 5/18/2014

    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.
