Fluval FX5 Canister Filter?

Is it worth sucking from both ends?

I turned my intake into a giant sponge filter to make or shrimp safe

thanks, i might give that a try then. i usually run 2 canisters so not usually a issue but might try only one big one on my 75.

sounds like he should switch to smooth vinyl tubing instead of using the ribbed tubing that comes stock

dj2606 For anyone else interested, this manifold also works on other filters. I wouldnt recommend using it on the ehiem classic filters because they don't have a self prime button.

I must disagree, canister filters are way easier to setup than sumps. However, my experience with them is linking 8 20L on 2 sumps (took 2 weeks to plump and was a PITA)

Ack! That should have been 5 gallons in *24* seconds, not 54. My mind...it's a terrible waste. Sorry and good catch! I figured it was approximately 600 gph.

Also, i like the idea of using two 45s instead of a 90.

Clownloachlover When building manifolds, spray bars, outlet nozzles or whatever, the other thing to consider, rather than using a 90 degree elbow to make a 90 degree turn, use two 45 degree elbows together...I cut 1" PVC to the exact length I need and then glue two 45 degree elbows together...it does not slow down the flow like a 90 degree elbow does...yes it takes up a little more room but in the end it creates better flow. I purchased some hose through an industrial hose supplier and it is smooth on the inside and ribbed on the outside with a plastic Helix coil...this stuff is super flexible and the 1" hose has a 1" 180 degree bend radius....Awesome stuff. The stock FX5 hose is flexible but with the ribs it does collect gunk on the inlet side and reduces flow rate over time.

here is the link to the hose I purchased part number...G941W...it is considered Water Suction hose

im pretty sure most filters list gph without any media. but listing the pump gph off the canister filter is pretty misleading imo.

i think im going to give this a try sometime, thanks ETK this is a great idea. i have a fx5 on my 125 and prob wont mess with that one. i will prob get a fx6 or the give one of the CFS a try. the lower flow is actually ok with me as it will be going on a 75g dutch style.

It is a little more complicated. The pump in the FX5 is rated at 925 GPH, but that is without hooking it up to the filter, so not really a useful number. The claimed filter circulation is 563 GPH, but even that is without any media in the filter (ie, water flowing through the empty canister).
04-23-2013 08:05 PM
shift I'm sure you could get rating that if the canister was 100% empty with real short hoses :P

Tenor1 There certainly are some VERY ingenious people here and I'm really impressed to see what people are doing. I would rather use 2 canisters and add some power heads in the tank to keep the water moving. The other thing is to under stock the tank and do more water changes. Water changes are the best maintenance you can do for a tank, IMO.
