hey its time for me to clean my filter and i asked my lfs
about how to clean it. I have a canister filter (eheim ecco 2234 or 2236 not sure. its green.). He said to put the cleaning pads i guess (he said whatever material you got in there) in the washing machine with half a cup of bleach and do a full rinse cycle in the washing machine. Then do it agian with no bleach. Im not quite sure if i should do this. the instructions say i just have to clean it with water.
