I put a rock in from my stream in my back yard, it was a black rock, shiny and perfectly black, I have had it in the aquarium for a long time and the water was always cloudy, In my bedroom I have a 20 gallon long with a gold fish in it, the tank was looking a bit boring so I took the black rock out of the 55gal and put it in the 20 gal, I woke up to discover my 20 gal was terribly cloudy and my Oscar tank was crystal clear... It was a dramatic change once I removed the rock
