How do you clean sponge filters?
Ok this might sound like a basic question but what's the best way to clean sponge filters. Do you just give them a very small rinse and remove surface gunk with your fingers or do you give them a real good rinse in aged water.
I've been doing a small rinse and just removing all the surface crap from the sponge. I'm thinking if you give them a real good rinse you'll remove all the bacteria. Is this the case, have I been doing it the right way or not?
Thanks.. Oscar
