There's a part of me that just wants to go to a smaller return pump, although it is reverse logic. In other words, let the return pump do what it is supposed to do -- return water from the sump -- and not be a supplement to flow. My Iwaki 30, even throttled down a bit, is ultra strong and pushes a pair of jets into the tank. I'd almost want it to trickle in... and let Tunze/Vortech provide FLOW to the tank.
I don't see the logic in reduceing the turnover rate of the water column.It seams you would see a decline in water quality?? Would you increase water changes to make up for this ?? Your tank looked great last time I saw ya and you had fantastic growth also.Why fix whats not broke?? I understand reduceing the noise,I must be missing something here Patrick-- Good luck
