Has anyone got any ideas on how to get rid of the tiny white bits floating in my tank ? it seems that when i turn off filter and air pump they float to the top . Also when i change some water it gets worse so i filled a glass with water and it seems to be in my tap water too which also floats to the top after it settles . I have a 54litre jewel tank with a jewel bio flo mini filter . oh and tank is still cycling so no fish yet . I would appreciate any feedback , thanks .
