Tunze, in my opinion, have always been the bench mark for controllable flow pumps in medium to large home aquariums. There is something about the quality of the flow that corals love and they simply keep going for years and years, especially the older models. They are expensive, but the best.
I got one second hand in 2008 when I was visiting weeman in the UK and the owner didnt know exactly how old it was, but probably 2 years by that stage. So its a pump thats been going since around 2006. Day in and day out. Not missing a beat.
But its been colonized and needed some repairs and maintenance. It stuck deep into a corner of the tank and out the way so I never relay bother with it, i know its not blowing its full water volume (i can see the effect in the tank) so a while ago i took the water guards off and ran it bare prop.
the Coraline encrustation on the from plate camouflaged it well in the tank, and was about 4 mm thick....
the actual impeller has been chopping through water so long its been warm away, im not sure how big it should be, but certainly not reduced to this....
and as i wanted to order a replacement propeller i needed to be sure of the actual model of the pump, which i couldn't even read off the back......
but i now know it should be pumping 12000l/h (perhaps i should lend it to vortex to see what its actual output is)
While I know tunze are expensive, to have a pump that takes this amount of abuse, carries on regardless and has served two owners perfectly over 6 or more years means I wont look anywhere else when it comes to quality internal pumps. Buy right once and you never have to buy again.
thank you tunze for German engineering where it relay counts in my tank.
