Started it today at 1 bubble every 3 seconds, wanted to see how efficient the EXT5000 reactor really is and already my pH has dropped from about 7.5-7.6 to 7.1-7.2, I'm using the Milwaukee pH 600 handheld meter. So far so good!
I did a kH test and it was at 7. But i've read that the kH vs pH graph to guesstimate the CO2 ppm concentration is only helpful if you have a carbonate buffer.. so I don't think this will help me considering I do not.
BUT, my discus haven't seemed to get affectedf, it is a closed top tank (for my cat to stay out of it! lol), so I run aeration 24/7. While my CO2 system is wired to the T5 HO light timer for the 10 hour photoperiod.
