Okay, got the pump installed today, what a PITA! No one had the correct reducer fittings I needed. This thing comes with big fittings!! 2.5 ID 3.0 OD. But trying to find reducer fittings, fugetaboutit So I find the reducers, primer them up and just as I'm about to push them together I remember the nut, that needs to go on or else it ain't going on! LOL, Okay so I get everything in, pump set in place and see that the PVC pipe connection to the output is off by a 1/4, enough to tweak it, but put a strain on the other end going to the filter, great, just great! So for the time being I tweak it in place and tighten it down, hoping to get lucky ( that didn't happen by the way) ready to hook up electrical, put the strain connector in and get 1/2 turn before it hits the fan case, no problem I'll just take out the two screws remove the fan case and be done with it, except that there are three screws and the third one is on the bottom, so everything comes apart again! Well anyway, it leaks at the filter side so I have to re-engineer the pvc (I hate working with PVC, it;s either right or it's wrong, there's no in between) but started it up and it was sheer bliss!! This pump is quiet, and I love the fact that at 750 RPM I'm using no more than 110 watts!!! Yippee!!! Now of course I have to adjust that so the wattage will be more, but so far first impressions are very nice! I'm still in the midst of programming it but I am very impressed so far.
