55Gal tank- Foggy..

I have a 55 gallon freshwater tank and after being setup it started getting foggy after about 1 week of operation, with no fish.. My filter system is the Magnum 350 Canister Filter. I have it setup using the blue Rite-Size filter sleeve over the carbon container. This filter has no by-pass, all water goes through the filter medium.


Thanks,

Yes my rocks were rinsed very well a few times under cold tap, and in a bucket. Also the water does have a current, you can see this by the waving fake plants and by the particles moving back and forth, such as fish food. However I also see things pass the filter and not get sucked up. But there is plenty of water coming out the "exuast" so I take it that its working right.

This towns water is going through an ionic water filtration plant, it doesnt use chemicals of any kind for filtration. Its the only plant of its kind in orange county. And the old pipes were replaced with new ones about 1 year ago.
