This is the third night for my tank to be running and yesterday I put in my betta. The water was fine alll day yesterday and was crystal clear. I dechlorified (sp?) the water before adding the fish as I let my system run for about 12 hours before inserting him. Today around mid morning my tank looked cloudy and has not changed at all. Also the bubbles from my bio wheel seem to all stay at the top and do not dissolve almost covering the entire surface area. The bubbles go away when ever I open the feeding hatch. Also, could any of this do with my filter already having growth on it from where the water runs. Thanks for the help.
