Alright it must be because your tank isnt done cycling yet and is caused from a bacteria bloom. You must have put too much fish (which needs a lot of fish food) and overloaded the bio-load in the tank. The bacteria that feeds on these excess food and poop is what makes the water cloudy.The water does not come out of the faucet cloudy. It might be from over feeding. I'll try feeding them less.
Yes, its a fairly new set up.
