Kellz, if you have water that is cloudy and has a green tint to it, you have what is called green water algae. It is single celled algae that grow floating free in the water and give it the tint you see.
I have tried in vain to grow it because it is a useful food for daphnia which I sometimes try to culture to feed to my fish. The only success I had was to innoculate a large tank of water outdoors, under direct sunlight, with a sample of green water. I then dosed that tank with a low concentration of ammonia as if I was doing a fishless cycle and in 2 weeks I could not see my hand 6 inches under the water's surface in broad daylight. The daphnia that I feed green water will thrive and reproduce readily but they remove all of the green water algae rather quickly from their tank. That means I need to maintain a separate source of green water to feed them. Once summer is over, my feeble attempts to grow green water indoors usually fail rather quickly and the daphnia end up dying out.
