I have a Redsea with venturi pump, DIY mix, small bubble constantly. How long would it take to build up the co2 to too much so the fish are ill? Juwel 180L
I left mine on all night and in the morning the fish were gasping and looking sick. Once aerated then remain fine and also fine during the day if co2 pump left on.
Might I be better switching co2 pump off during night and just leave the odd, say twice a minute large bubble to plop out.
Just thought, wow tank has soon filled up with co2 overnight.
thanks
