- 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. The 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 and may not last as long as spherical media, but is much more effective.
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.
How Long Does It Last?
Since every aquarium and the environment around it is different, the amount of media used can vary greatly from one home to another. In most cases, BRS CO2 Absorbent Media will last up to two weeks per single 10" cartridge, but depending on the amount of CO2 present in the air around your tank, the lifespan of the media will vary. Keeping the carbon dioxide levels in your home lower will help increase the lifespan of the media, which can be done by opening windows and using screen doors allowing fresh air inside your home. Another great option is live plans inside the house which will help minimize CO2 levels as well.
Not as good as the old stuff By Ray on 3/18/2019Ray wouldn't recommend this product to a friendThe new CO2 scrubber is no where near as good as the old spherical product. Problems I’ve noted after using it for several months - their is much more dust that has caused caking within the scrubber cartridge. The color change is MUCH fainter than the spherical media resulting in throwing away still good media when I couldn’t tell through the cartridge if it was expended. Also it seems that the media is used up faster, though I don’t have hard data to prove it. BRS, please go back to the old spherical media, this stuff isn’t up to the task.
It works fine but very short life span By Robert on 3/15/2019Robert wouldn't recommend this product to a friendIt works fine but the life span is very bad compared to the older pellets. Please bring back the pellets
Disappointed... By Steven on 3/5/2019Steven wouldn't recommend this product to a friendI have beenusing this product for about 2 konths jow, and thr media dors not last, as I am having to change it less than 2 weeks, previous brands imI have used lasted juch longer and kept my pH much higher. Typically BRS brands are reliable which is why I switched to it in tbe first place, my mistake. Once exhausted, I do not intend on purchasing this product again.
Good stuff By Corey on 1/24/2019Corey would recommend this product to a friendRecently put this in a cheap media reactor during the winter months to keep my ph up. My ph now stays at 8.3 oh higher even while using a carbon dosing method. I noticed alkalinity consumption increased over the course of a week. I also put a valve on the intake and output of the reactor so I can only use it at night when ph is lowest. This allows for the absorbant to last longer. I only use it when I need it.
New Formula By Jamie Segner on 11/29/2018Jamie Segner wouldn't recommend this product to a friendI have been using this product for about a year now. About a few months ago BRS switched to a new formula and as another reviewer has said the new formula works but doesn’t last as long. The old formula would last two weeks, the new formula last about five days now. A little disappointing consider it last roughly half as long but the new formula isn’t half the price.
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.
