It's clear that Fluval owners haven't had other brands of filter when they say they are easy to work. Relative to some things, yes they are easy, but if you compair to other exturnals, they are one of the worst to work. Lets look at the priming procedure of each (I have had both these brands) of Fluval and Tetratec set-up
Tetratec
Cut hoses to length
Plumb up and check the taps are open
Press the prime button once
Make and drink a cup of tea while it fills
Plug it in
Done
Fluval
Cut hoses to length
Plump up and check the aquastop is open
Give yourself an arm ache pumping the self priming leaver that invariably does not work after the first few times, then when you realise that is not going to work...
Remove the outlet pipe from the back of the tank, positioning it over a bucket below the tank
Suck the outlet pipe
Wait for a bucket of water to syphen through before closing the aquastop
Re-position the outlet
Plug in
When the impeller jams, kick it right on the MSF badge to try and free it. If it does not work, kick it again,
harder. If it does not work this time, swear a bit, empty the canister and go back to step 3...
When you get the airlock, pick it up and shake like crazy...
Now you are hopefully are done and can go get that well deserved up of tea...
Just for good measure, just in case Tetratec are rediculesly easy to work...Priming a Rena
Cut hoses to length
Plumb up and check the quick release leaver is up
Fill inlet pipe with water, via the funnel, before re-seating the cap onto the inlet pipe-set
Press the quick release leaver down
Make and drink a cup of tea while it fills
Plug in
Done
A tad more drown out than a Tetratec, but still easy relative to the Fluval
All the best
