co2 - is there possibly a limit of ppm?
I was a little confused today looking at my bubble counter on my co2 tank. I have normally kept it at 3bps (180bpm), which has always yielded me a co2 reading of 45-50ppm. no problems to the fish, so never felt like reducing it. the co2 reading came from 6.6pH and 6KH.
today, I noticed that it looked like a constant flow of bubbles was flying through my bubble counter. upon the best attempt at counting the bubbles I could, it came to 5-6bps (around 300-360bpm). I did not however see any change in my pH level, and KH was the same as usual. So, still had a co2 45ppm reading. no ill signs from the fish either.
I am not sure why my Regulator wont maintain a bubble count, but obviously need to get it fixed.
Just confused as to why my co2 reading didn't sky rocket. Almost like any excess co2 bubbled out (maybe doesnt have time to fully dilute in my reactor). Could this imply that there could be a limit of co2 in certain situations... obviously tank/setup dependent?
