If you put some of the water in a cup is the water tinted green? If so that is an algae bloom. If you do a WC and the water clouds back up this indicates a bacterial bloom. Both will return (if it is indeed one of these two things) even with a very large WC because the algae and bacteria will still be in the water that didn't get removed and will cause the tank to have the same issue. A UV sterilizer is the fastest way to eradicate both of these problems. Also how long has the tank been set up?
