My 55g tank is not crystal clear after 7 weeks of existence and weekly WC, the water has white floating particles. I have upped the WC to 5 in the past week and I thought that would do the trick but it hasn't. The tank is planted with 40 fish and the quality of the water is good. Some algae does grow on the sides but since the 5 WC I don't find much there. Here's a pic to show the floating particles. Any advice is welcomed.
