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.

Recently changed mine out and put the used purple pellets in the trash. When I came back an hour or so later, it had all changed back to white. Does this media recharge? Did I simply not use it sufficiently to completion? What are your thoughts?
Question by: Stephen Fast on Dec 17, 2016 11:47:00 AM
Great question! The media will not recharge on its own, but may change appearance after usage. We are currently testing ways to possibly recharge the media, but have not dialed it in completely just yet. The biggest indication of exhaustion would be a change in your pH, along with the color change. :-)

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.
Answer by: Connor (Admin) on Apr 29, 2016 9:08:00 AM
I bought the media with the brs reactor couple weeks ago since then I changed the media 3 time already. each time only last 3 days then it turned purple.
Why it exhausted so fast? Is my skimmer pulling too much air? (Skimz sm162) I tried running airline tubing from reactor outside still the same
Is there anyway to prolong media exhaustion? Otherwise it'll be real expensive for me.
Question by: tanasate Nakasatian on Dec 30, 2016 6:36:00 PM
Great question! Media consumption will be varied dependent on your ambient CO2 levels. If you have higher CO2 in the ambient air, you will consume media quicker. We have limited our CO2 media consumption by regulating when the skimmer pulls air from the media reactor. You can view our methods and explanation around the 6min mark on the video below! :-)

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!
Answer by: Connor (Admin) on Jun 14, 2016 5:50:00 PM
Can I mount the reactor sideways? I see you have to add 1 teaspoon of water.
Question by: Rich on Dec 12, 2016 5:08:00 PM
Great question! You could install this horizontally. The space between the internal cartridge and the canister would still allow for water to be added. :-)
Answer by: Randy (Admin) on Dec 13, 2016 2:37:00 PM
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.

  • Raised PH 0.2 By Adam on 7/10/2017

    I have two dogs in the house and we live in the hot Arizona environment so opening windows and doors is out of the question. I placed the media with the CO2 scrubber and it raised my tank PH from 7.9-8.1. So it worked as I had hoped. The only thing is that the absorbent will last maybe two weeks then it needs to be replaced. This could be costly long term. Go with the BRS team suggestion and try to run the absorbent only when PH drops if that's a possibility. I've since ran a hose outside connected to my skimmer. This has helped a lot with stability and my wife can't see the holes so she's cool with it.
  • Did not work on my tank By Kurtis on 5/7/2017

    I have trouble with PH it is always at 7.8 so I chatted online with BRS and they told me I needed to use the Co2 media. I have used additives that will raise the PH but then the PH just falls back to 7.8 within 12 hours, and then with the additives the Alkalinity goes thur the roof. So with that being said I followed BRS suggestion on the Co2 media, after 2 weeks and changing media when it changed color I STILL have the same problem and this media did not change my PH at all. So with that being said I now have a $50 gallon jug of this product that I will never order again.
  • DID NOT WORK ON MY TANK By Kurtis on 5/6/2017

    Problem I have is the PH is always at 7.8 and using PH increasing additives will increase PH but within 12 hours my PH is back to 7.8 and with PH additives your Alkalinity goes thru the roof. So I did online chat with BRS and they suggested the CO2 absorbent, so I gave this a try after 2 weeks and changing media when it turned purple, my PH is still at 7.8 so unlike the dozens of reviews of people having overnight success I was not one of those. Now that I have a $50 gallon of this product setting in my home I will not order anymore.
  • Works but expensive!! By BadabingNC on 4/7/2017

    I use with an old BRS reactor, on my 55 gallon tank it lasted about three months, but with my 110, and a bigger skimmer, it won't last half that long, might be too expensive to keep buying!
  • Works well but $$ By Buzzword on 2/21/2017

    It worked great from the start. pH went from 7.80 to 8.10 to 8.2 at night to 8.35 during the day. That said I had to change it every week which was going to get expensive. So I use the CO2 scrubber to the skimmer at night to keep pH swing minimal and ran a line from outside to my skimmer during the day. Keeps pH from 8.1 to 8.35. Now only changing it every 10 days to 2 weeks.
  • AMAZING By mark on 2/5/2017

    I have a 220 gallon tank. I have tried just about everything out there to get my ph up. with in 48 hours i was at a 8.3 my tank has ran at 7.8 to 7.9 since i set it up 6 months ago. i was tired of doing huge water change. trying chemical. it would always raise up then fall back to 7.8. i had a old media reactor laying around and figure i would try this stuff. i can finally add my calcium reactor and feel better about my ph levels.
  • Great product By Luger on 1/27/2017

    I have used this product on my skimmer air intake and it has worked extremely well. It has kept my PH between 8.2-8.3. I change it out every week as its looses its effectiveness towards in about that amount of time. I use in conjunction with a two part dosing regime which I have on dosing pumps.
  • Works well, but its pricey By Bryan on 10/25/2016

    Works as described. Keeps pH up with my Calcium Reactor and low tank pH. I have to change it every 6 days though so its got a high price tag associated with it. I might try extending the intake line to a different room in conjunction with this product in order to extend the life.
  • PH up and stable By Jeff on 10/1/2016

    before I started using the co2 absorbent my ph was a low of 7.85 & a high of 8.15. Now its 8.09 overnite and 8.30 during the day. Great stuff and lasts longer than I thought it would.
  • IT Works! By luke on 9/27/2016

    Running on JBJ 28 gal NanoCube through Reef octopus HOB 90 cone skimmer air intake.

    Ph consistantly at 8.3. This product raised my ph to 8.3, and as a bonus eliminated the ph swing.

  • 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
