i got my fluval 404s in the mail i only have one set up right now running with my hob but what a great filter the flow of water is amazing very nice canister and media baskets the only problem i had was those darn suction cup hose brackets and the little rubber bands that hold the hoses cutting out my background for the suction cups was no fun and the rubber band gimick is cheasy but i am very happy with the filter thankyou all for the help

yee, they are good filters. glad your happy:)

Is there a trick when you clean out your tank and filter to get the Fluval 404 to start circulating water? We have a 404 and a 305 and it seems like it take forever to get circulating no matter how many times we prime it. I think we must be doing something wrong or missing a step. It eventually starts circulation but takes at least 15 -30 minutes to start flowing.

Make sure there isn't trapped air. If you run the pump with air around the propellor you can shorten its life as its ceramic coated.

i actualy have 2 fluval 404 i have the same problem what ive been doing is filling the caniseter with water and then putin the head on it seems to help alot but still slow to prime

yes that's the best way.fill your canister with water, when you have filled the canister, put it back together then siphon water into the canister by your out flow or input hose. this will make sure the canister and hoses are full of water with no air.you can tilt canister toward the hose you siphon so any air can escape. or you could fit a funnel to 1 hose and tip water in. the idea is make sure canister and both hoses are full with water.then turn filter on.

Thanks so much. Glad we arent the only ones having that issue...thanks for the advice and tips, will be using those tips tonight...thanks again!!!

anytime glad i could help
