Hello, I'm brand new here, so... Hi. Way back in my university years, I kept a 20 gallon aquarium. Ihad it for approximately 6 years. Well, yesterday I finishedsetting up a 10 gallon one. It has 2 Dwarf Gouramis and 3 Platies.That's neither here nor there as regards my question. In ONEDAY my tank went from crystal clear to very cloudy. I tried thatcommercial 'de-clouder' to no effect. I'm at a loss. I am notdoing anything different than when I had a 20 gallon 20 years ago. Iam thinking of changing the pump as I bought a low end one - but ONEDAY?! I'm going to begin a complete water change tomorrow and supposeI'll be stuck doing so until I get a new pump. What do y'allthink of these (non-UL to begin with) 'Tetra Whisper Air Pump s?' It sits on the bottom and looks like an alienspaceship. Are these superior? Now I have an AqueonQuietFlow filter. Cut and paste either name into Amazon ifyou're unfamiliar. I'd PREFER the old fashioned AqueonQuietFlow kind that hang on the outside and create littlewaterfalls. ANYTHING else I may be missing? Frankly, HELP!!! Thanks, Panoply PS: I ordered a fancy snail, but it's nascence shouldn't bedoing this!
