- Color Changing CO2 Absorbent Media - Bulk Reef Supply
Raise your Reef Tanks pH by controlling Carbon Dioxide!
Bulk Reef Supply Color Changing CO2 Absorbent Media (Soda Lime) is the perfect solution if your aquarium has a low pH but proper alkalinity levels. It is most commonly used by connecting a carbon dioxide scrubber to your protein skimmer's air intake and can produce substantial lifts. We package the media in Mylar bags and then seal them to preserve the hydration of the media, leading to longer service life and the ability to absorb more CO2 than others on the market. We suggest purchasing single cartridge refills, but if you have higher carbon dioxide levels in your home or business the bulk packaged media is going to be more economical.
- White to purple color change indicates depletion.
- Minimal dust levels due to the high surface area and graded particle size.
- Reliable control of indicator dye concentration.
- Resistance to dry gas desiccation minimizes the risk of CO gas formation.
- Doesn't contain potassium hydroxide.
- Packaged in Mylar bags to preserve the hydration state.
Two Sizes Available:
- 1.2 lbs - 1 Single Cartridge Refill (approx 800mL)
- 7.5 lbs - 7 Single Cartridge Refills (approx 5600mL)
7.5 pound bulk media comes in a resealable mylar package
BRS Carbon Dioxide Absorption Media is made of calcium hydroxide (Ca(OH)2), water, and a small amount of sodium hydroxide (NaOH) in a precise mixture that will efficiently remove CO2 from the air in a semi-closed system. An addition of ethyl violet dye is added to the particles as a color indicator to show when the media is nearing exhaustion, making maintenance as easy as looking at the canister containing the media periodically. The irregular shaped granules add to the available surface area, allowing more air to media contact time, while the granules also fill any voids and help minimize channeling through the cartridge.
Instructions for use.
1) Fill your reactors refillable cartridge with BRS CO2 Absorbent Media
2) Add one teaspoon of water to the bottom of the filter canister housing (not the cartridge). Do not get the soda lime wet.
3) Connect the output of the reactor to the intake of your skimmer.
4) Keep an eye on your aquariums pH and the color of the media and replace the media after it has turned purple or the pH is starting to drop*.
*It is essential to replace the media after it has exhausted. If exhausted and left to stand CO2 absorbent media will revert back to a white color, and may appear fresh but is actually not usable anymore. BRS CO2 absorbent media cannot be regenerated and should never be re-used.
A few things.. By Lizby on 10/26/2018Lizby would recommend this product to a friendI was using the Two Little Fishes CO2 media and really liked it. The size bottle is the perfect size to properly fill the average reactor and if saved, the empty bottle provides the perfect way of disposing of the depleted media. Dumping used CO2 media in the drain or garbage can is a bad idea but if you put the used media back in the empty bottle, disposal is safe and clean. Also, the TLF media goes from white to dark purple. The color change is drastic and moves steadily down through the media.
I bought the BRS media because of the price and all the glowing reviews. First, the BRS media comes in a large foil bag so I have to use a cup to dish the media out. Also, the color change is so slight that I couldn’t even tell it had changed at all. I had the reactor filled and hooked up for a week and saw no color change. I called BRS because I was afraid my batch was defective but was told that the BRS media was designed to last longer and I may not notice a color change as quickly. Another week or two went by and I still saw no visual change but when I tested, my pH had plummeted. I pulled the reactor out and looked at the media. I had to put a piece of white paper next to it to tell if there was a color change. It was so slight you could hardly see it. With the reactor under an aquarium cabinet, I have no hope of knowing when to change the media.
Maybe I got a bad batch. I don’t know. But I think I’m going to go back to the TLF media. As much as I love BRS and their products, this is one I won’t likely purchase again.
New Formula By Tom on 10/12/2018Tom would recommend this product to a friendProduct works but the new formula doesn't last as long. I went from a 7 days to 4 after the switched.
Great product By Shark bait on 10/9/2018Shark bait would recommend this product to a friendWorks great.. raised ph in about 6 hours only suggestions I have is mabye a clear canister so you can see the color a little better. I have found an old clear one and swapped it out works great
Best Purchase EVER! By Robert on 9/7/2018Robert would recommend this product to a friendI live in San Diego, and my tank is in my well ventilated living room. I tried reverse lighting adding macro algae, dosing additives, improving flow and water changes. All with limited and temporary success. I could not get my tank ph over 7.85. My pH would fall to 7.45 during a nocturnal cycle yand my tank hitting a pH of 8.0 seemed like a fantasy. It was very frustrating. My tank parameters were well within the accepted norms. It simply made no sense. This was my first thought but was persuaded not to by my LFS. I finally cave. I am so happy i did. Now my pH is consistently between 8.1- 8.2 . I wish there was a larger media size.
Best pH Fix out there! By Gil on 8/24/2018Gil would recommend this product to a friendSo glad to see this back in stock! The new media is working great, and the price is so much better. That was my only complaint before. There's nothing better for keeping my tank's ph stable and in the proper range.
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 5/6/2017Kurtis 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.
