I have a 54 gallon AGA RR corner tank. I run a 700 gph return pump and have a 50 and a 300 gph powerhead in the display. The return is angled to move along the the side and across the front curved glass. The small PH is placed on the side that the return flows along towards the front of the tank, about half way down from the top and is flowing below and diagonal to the return. The 300 gph PH is on the opposite side from the return and converges with it near the middle of the front of the tank. I am considering replacing these 2 PH with the 6025's. (I believe I would recoup the purchase price of the pumps in 1.33 years just in the cost of electricity to run them. This does not account for the cost savings in chiller run time during the warmer months of the year.) Do you think that 2 of the 6025's would be overkill in this tank?
