So, i've had my 55 gal tank setup here in my basement for about 14 months, and it always seems that there is particles of something floating all over in the tank. the only thing i can think of is that it would be from the flake food maybe. i can only describe it as it looking like its always snowing dust inside the tank. i know it sounds stupid but maybe someone could tell me why its always like that. thankkks.
