I was thinking about using the water blaster 2000 for a return pump on my 45 gal tank with a 30 gal sump/fuge(i am guessing total water volume will be 15-20 gals). I am looking for about 150-200 gph turn over in the sump. Would the 2000 be able to do this pumping up about 4-5' or would the 300 be better? Or sould I go with a diffrent pump?
