I originally set up my new 36-gallon aquarium without washing the sand and had serious cloudiness problems. I emptied the water and washed the sand, but the water was still cloudy after a week. I tried adding water clarifier tonight, but it made the cloudiness notably worse and this hasn't cleared up after several hours. The directions said the water would get worse but then clear within one to two hours.
What should I do? Should I start over with gravel?
