Shelf life of BRS CO2 scrubber pellets?

dangros · Sep 28, 2017

about a year and 1/2 ago, I purchased the BRS color changing co2 absorbing pellets in an attempt to raise my pH. Not only did it not work but it also never changed color! So I gave up thinking co2 was not an issue in my living room. I started noticing the pH dropping a good bit recently so I tried leaving the window near the tank open at night. It made a slight but definite difference. So, I want to try the scrubber again. How long is the media good for? It's in the same container now for almost 2 years.

I can't answer the question on the shelf life but I will say give it a chance. I hooked up a BRS reactor to my skimmer with the pellets and it was night and day difference. My PH went from hovering around 7.8 to never dropping below 8.0 unless the media needs to be changed. I now have an alarm set up on my Apex alerting me if it drops below 8.0 so I know when to change the media.

If the media was tightly sealed from air entry, it is likely still good.

As long as it has been sealed tight and hasn't changed color, you should be good.

I have been using medical grade CO2 scrubber media with great result. It is way cheaper than BRS media

@roberthu526 where are you getting it from?

So I gave the co2 scrubber another shot at about 9pm last night. Note the upper right side of the graph. Ph stopped dropping immediately. Soon as the lights went on this am, up it went. Still going up. For the record, I am using the BRS media in a Phosban Reactor 150 with a teaspoon of water at the bottom.
