Hey i have had a filter sock for about a month now and i have been just running it under water. It doesn't seem efficient enough because it still has a blackish tint to it. I have read to turn it inside out then wash it with bleach in a washing machine. I want to know the most efficient way in cleaning a filter sock please. Thanks all.

Hey fellow addicts. I got a new 55 gallon pre drilled tank and stand that came with two holes in the bottom of the tank and came with two bulkheads and pipe. I have it all set up and need to figure what return pump I should get. Any advise? The overflow hole is 1.5" and the return is 1''.
