I have been using this Tank Stabilization System thing and I think it is making my tank a little cloudy. My goldfish are acting completely normal but the tank is a little cloudy. I am pretty sure it is the stability thing because what else would it be? I am feeding them flakes, that shouldn't make it cloudy. Should I stop putting in the Stability stuff? Do you think that's making it cloudy? Plz answer, thanks.
P.S. this is the stuff I'm using

It will make your tank cloudy for a little bit, for me it's like 18 hours. so don't worry.
