i have a 300 gallons tank and My PH right now around 7.9x and i'd like to boost it to 8.2/ 8.3. Dont want to use the kalk mixing. I think CO2 scrubber is a good solution. If anyone has any CO2 scrubber, pls let me know.
i use the color changing one from BRS as it is color changing and can be recharged. my system goes through it pretty quick so i would buy enough to keep some back up stock
