Guys, i just bought a 6 gallon tank with florescent light and bio wheel
filtration 8 days ago.
and already it's cloudy. a lil greenish.
what can be the reason and what should I do?
the fish store guy told me to turn off the light for a few days.
I tried that but didn't seem to help?

I have:
7 baby guppies (friend gave me)
1 male guppy
4 neons
2 serpae tetra
2 mickey mouses
2 coreys.

also added cycle nitric. but didn't help at all too.
help... THANKS!!!!!!
