You only have to drill holes with wet/dry sump systems, not canister filters. The intake and outtake lines go behind the tank to the canister underneath the tank. You will need to make a one time purchase of the bio media, such as Biomax ceramic rings. The coarse sponges usually come with the canister from the factory. The sponges can be rinsed and reused over and over, and the bio media generally doesn't get rinsed or cleaned. You don't need carbon or any type of ammonian remover etc. The only thing you may want to add is some filter floss (pillow stuffing bought at walmart). I put that in my top tray and it's like $4.00 for a big bag. So after your initial purchase, there are very few things you need to buy. Cleaning is only needed about once every couple of months. When you first set it up you can let it go longer than that before your first cleaning. I'll find some websites and post up the links.tarwi said:do you have to drill holes in your tank etc? where is a good website to research canister filters. I would need one that is not complicated and hopefully not where I have to keep messing with it like replacing stuff in it often, maybe one thats also somewhat affordable?
I think they are even better now since the 04 series came out. I have a 305 too. Both that and the fx5 have been great.JoelRHale said:With all of the praise of Fluval products, I am looking forward to getting my 40L up and running to use the Fluval 204 that came with it. It was a pain to clean but I may have spoke too soon.
