Hey guys,
I just recently got a Ehiem Professional Filter II
the thing is a got it used from a friend of mine and its empty. The only question i have is what sort of media should i put into this Filter. There are so many carbon things for nitrates things for phosphates, bio things filter floss. i really dont have much clue.
Im going to set up the filter so it siphons water to the canister and out into my sump just so i cna get a double fulter thing going on
thanks!
