Hey all. I will have a Fluval 204 arriving next week from someone on TFF, and its comming without any media (as you might expect). I'll be adding it to my 180 litre tank to go along side my Tetratec EX700 to almost double my filtering capability! (Knew I should of got an EX1200!) Currently the tank is medium stocked, lightly planted (this will change) and the EX700 has standard coarse/ceramic hoops/bioballs/polishing pads in it. Anyhow, I was wondering if I should take the oppertunity to load it up with some specific media for either bio or mechanical filtration but I was looking for suggestions as to what setup would serve me best?
