Fish Tank Keeps Getting Cloudy

how to keep fish tanks from clouding?

I have a fish tank and in it i have 3 fish. 1 full grown goldfish, 1 baby goldfish, 1 black moor. The water in my fish tank seems to get cloudy quick, i have to clean it once a week is there any way to keep the water from clouding? And also, is purified water safe to use in the fish tank with tropical fish?

Not to be gross but goldfish poop… A LOT. A filter is your best bet. There are cheap ones for small tanks, I have one, and I think it was about $6, and I have had it for years.
