When I started up my water had a whole lot of tiny air bubbles BUT after a day or 2 they went away and the water was 100% clear. Now 5 weeks later they have come back and I was wondering if it has anything to do with the water. I have a spray bar from my cannister which sits just above the water line. I know this has something to do with it BUT is there anything else I need to test for in the water such as chlorine ect ect. (I did a 30% water change 2 weeks ago, but conditioned it) It just looks really crappy with all the bubbles and because they were not there and now have come back I thought something might be up with the water.
