Fish Tank Green Cloudy Water

Why is the water in my 2.5 gallon fish tank still cloudy?

I have a 2.5 gallon fish tank and I’ve had it for about 3 months. I have 3 fish in it, but they are all pretty small and they’ve been living in there together for a month and a half before the water starting turning cloudy, so I don’t think it’s too many of them in there. It’s white cloudy, not green cloudy, so I know it’s not an algae thing.

I thought it was a bacterial-recycling thing, so I’ve been changing about 30% of the water once a week like someone on Yahoo answers told me to do, and it still hasn’t cleared up in a month. The fish look fine, not sick or anything, but the cloudy water is bothering me. What else could it be if not a bacterial bloom?
I have about an inch of gravel on the bottom of the tank already, and I have 2 fake plants in there, but that’s it.

I do suspect it’s a bacteria bloom due to excessive ammonia in your tank. Cycling a tank mean, giving it time for the bacteria in your tank to grow to enough number to manage the bio-load of your tank ie. your 3 fishes. And if you’re right about the duration, 1.5 months should be sufficient for your cycling to complete.

The thing is I suspect that you have a gravel-less tank with some plants and a small filter that is without ability to hold bio-media.

What I am hinting at is that there isn’t enough place in your tank to host enough bacteria to support your 3 fishes.

If that is true, you can maybe add an inch or 2 of gravel into the tank to increase the are to host bacteria. Or alternatively you can drop some good bio-media into your filter. And that should help too.
