I added live sand to my 75gl aquarium last night. The water is extremely cloudy even about 16 hours later. Is there anything that I can do to help things out? I just turned the pumps off to see if that will help at all. This is a new setup, so no fish are involved. I wanted to add some more live sand today; 60 lbs is barely covering the bottom of the tank. What is a good way to add more sand without prolonging the cloudy problem?
