I run a co2 scrubber on my skimmer and wondering if anyone else has this issue. Whenever I feel like the media is exhausted and replace it, it takes almost a week or so to start working effectively again. Currently this media I’ve had going to 2 weeks. Last week ph never peaked above 8.3 and the drop at night is more. Now this week it’s consistently peaking in high 8.3s and doesn’t drop as low. Everytime I replace it the cycle restarts. Could I just replace half and see if it works? Not sure why this is. Not a huge deal just curious. Anyone else experience this? Scrubber is brs with their media. Thanks all
