Cloudy Water

[CoPz]

I have merky water and I don't know why...could it be too much Co2 in the water?? My fish seem fine though! It just all of a sudden went merky(cloudy) How can I visually tell if there is too much Co2 in the water?

Hi, my tank went cloudy too with the addition of CO2. I don,t think its a problem, just the tiny bubbles making the water look cloudy. Visable signs of too much CO2 would be dead fish. You should always monitor CO2 levels either with a monitor or the CO2 chart. 15-20 ppm are ideal.
