Im using a HOB octopus skimmer its a bh-100, and ive always had algae problems. Sometimes its a lot sometimes not as much but theres always SOME... well as i was emptying out my collection cup today i looked in the skimmer, and it came with this piece of sponge thats like 2x2x2 inches that wraps around the pipe that dumps water back into the tank. Well this sponge is NAAAAAAAAAASTY, like it looks like its covered in brown, nasty gunk... its FULL of it. Ive never looked at it before and now im starting to think that maybe this is why my water quality is helping algae grow. Could something like this raise phosphates? Should i remove this sponge all together??
