I have a Fluval U2
I'm modding it (see other thread if your interested)
Basically in the two outer cases im removing the carbon preset, and replacing it with poly sponge (think its called that ) its the finer sponge. So would it be best to have the finer sponge make contact with the water first (outside) or second (inside)
I hope this makes sense!
Cheers
