Just got the 750 up and running. I am using a 135 gallon sump with a Ultima 2 pond filter with one Dolphin ampmaster 3000 and one ampmaster 4000. This tank has so much water going through it that it sounds like Niagra falls in my overflows. I might have to tone it down some. It is in my garage, so I won't hear it anyway. Now the dreaded waiting of the cycle begins until I add any expensive fish. I will update when fish go in and decor.
