I use a medium IceCap CO2 scrubber plumbed to my Aquamaxx HOB 1.5 skimmer. My tank does not drop below 8 at night and gets as high as 8.24ish to 8.3ish after my daily manual dosing. Before using the scrubber I would hover between 7.7-7.9 and it would drop considerably at night. When I first started to use the scrubber I would only get two to three weeks on the media. Then I saw a post here on the forum that said adding water to the scrubber would increase the humidity and allow the media to absorb more. So I make sure there is always 20ml of water in the bottom of the scrubber. I went with 20ml because that’s the syringe I had. Making sure there is constant water in the scrubber has allowed me to go 4 weeks, from Sept. 18 to Oct. 17, on the same batch of scrubber media. Why did the water help? Does it increase absorption? Any ideas!
I really want to maximize my media usage. I know I can make the scrubber recirculating but I’m not sure I need to. Here is a graph showing the last couple days of that 4 week period and the start of the new batch of CO2 media.
