I guess everyone is entitled to their own opinion. But I've found cleaning my large canister filter every 3 weeks takes approximately 10 min, maybe less. Good luck cleaning a big sump in 10 min or less..."Pulls a lot of suspended waste"....yes
"Easier to clean".....no........I ran a FX6 for 17 years. To pull out the canister from under the stand, drain and then open it up to clean the contents was a lot of work BUT it is doable. With a sump, it's open...the only thing that gets cleaned is the filter socks and that just requires me to pickup and replace sock.
Why would it be trouble on a FOWLR?I have experience with 4 different types of canister filters, FX filters from Fluval, the Eheim, Sun Sun, and some XP star filter. The common theme is that they have no flow indicator, no way of you telling if its clogged or not. So you must do it on schedules.
Just like filter socks, they don't remove anything from the aquarium until the filter itself is cleaned. At least with filter socks, I can load up on 20 of them and change them out daily. Cleaning a canister filter daily is not possible.
Running a cannister filter on a fish heavy tank means a lot of poop. That means more filter cleanings, more salt mix, more time, more advil and heat packs for the sore back.
Canister filter has its uses. If I ran an established reef or planted tank with very minimal fish, I think its doable. If it was a FOWLR, you are asking for trouble. On the FX6, don't believe it when it says good enough for 400g.
To siphon the detritus out of the bottom of an entire sump? And remove accumulated salt creep, etc? In less than 5 min? That's inhumanely quick.takes me less than 5 min now with a sump
Looks like a printer lolapparently even Fluval thinks the FX 6 is old tech now.
They have an advanced new model which has the removable and independently cleanable prefilter like Oase does.
that said, if an FX6 works for you, of course one should keep that......
Forgot to mention… and possibly a bit controversial don’t change or clean them too often! Do of course clean and change but don’t go mad… if the tank is happy then leave it be. The water changes take care of most thingsDefo agree but with a caveat, I’m running 3 nano tanks all at different ages now and at different sizes and all on canisters. I find they do the job ace but you do need to go heavy on the rock and keep on top of water changes!
