Thanks uhm i have a 20 gal tank and i have a bio filter in my 20 gal i have four plastic plants and a declaration peice and a buble stone (i think thats what it's called *twirlysmi) well any way i've had the bump going four about 5 days now and the water is cloudy i used sink water and i but in the purifier and everything and i also purchased a chemical to make the water completely clear but it's not working. i want to know if the waters cloudy cause of my biowheel or something else.
