I got my fluval 204 for my 29 gallon on Friday. Is it just me or are these things hard to put together. Not the canister so much as the hoses etc. I was working for an hour straight and was in the home stretch (putting intake and outtake hoses on tank) and I ended up with one hose to short. (my bad). I called Hagen and of course they were closed for the Good Friday. I called Drs Foster and Smith and they did not have the ribbed hose part for the 204 ( I ordered the filter from them?) so I went online to Big Als and thank goodness they had it so I ordered it. My advice to anyone who has not had canisters before is to have someone who has, help them with the setting up and installation. It is alot harder than an HOB. What a fustrating day!
