- Color Changing Medical Grade CO2 Absorbent - Bulk Reef Supply
BRS Color Changing CO2 Absorbent is low dust, medical grade soda lime spheres. Contains a special Zeolite to reduce the risk of drying out which results in media lasting longer. Uniform shape for more even flow. Changes from white to purple as media is depleted.
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 lifespan.
- 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 affecting 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.
Nine (9) lb. jug will give you seven (7) standard cartridge refills.
Great stuff By Justin on 5/11/2018Justin would recommend this product to a friendThis stuff is great but it can be a little pricey but so important to have in any efficient home that traps CO2 in the house. After using this stuff, my pH went from a 7.8 -7.9, even as low as 7.65 to a higher range of 8.05 at night and a high of 8.20 during the day. So worth it to keep my pH up in my tank!!!
Does what it says By rtparty on 4/18/2018rtparty would recommend this product to a friendI feel the only fair way to review a product like this is to ask: Does it do what is claimed? Reviewing it on price, how long it lasts or anything like that is unfair and incorrect in my opinion.
It is pretty safe to say that the science says this media will remove CO2 and that is proven. If if it didn't work on your tank, chances are very high you implemented it incorrectly, your testing device is broken or you have larger problems that need to be resolved. The media comes well packaged and easy to use. It changes color when depleted and is scrubbing excess CO2 from the air it is drawing in. Pretty simple. You can't knock the product because you don't like the price. If it is too expensive, don't buy it.
Worked overnight By Walkreef on 4/14/2018Walkreef would recommend this product to a friendMaybe I got lucky, but my ph went from a steady 7.9 to a 8.1 overnight. Wish the media lasted longer.
BRS CO2 ABSORBENT By Frejr on 4/8/2018Frejr would recommend this product to a friendThis stuff works great just wish it was cheaper.
It does work great By Bakerrichard27 on 9/1/2017Bakerrichard27 would recommend this product to a friendIt works great this brand just does not last as long as the medical grade stuff I got off eBay but it does work flawlessly
Raised PH 0.2 By Adam on 7/10/2017Adam would recommend this product to a friendI 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 5/7/2017Kurtis wouldn't recommend this product to a friendI 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 5/6/2017Kurtis wouldn't recommend this product to a friendProblem 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 4/7/2017BadabingNC would recommend this product to a friendI 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 2/21/2017Buzzword would recommend this product to a friendIt 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 2/5/2017mark would recommend this product to a friendI 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 1/27/2017Luger would recommend this product to a friendI 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.
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
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 :-)
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!
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.
What is the shelf life of this product? I love to stock up and keep a large supply of media on hand, but I want to make sure it doesn't "go bad" before I use it.
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?
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?
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.
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.
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.
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!
Can I mount the reactor sideways? I see you have to add 1 teaspoon of water.
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?
The co2 absorbent unfortunately is only for removing CO2 from air. It can't be used to remove the CO2 from your water unfortunately.
