Hi Tim,

AP recommends a pump to cycle the FT tank volume within one hour. 295 gph is close enough, but if you have to factor the head height, which will lower the turnover rate..............all this has to do with adequate O2 for your fish ratios. At 65 fish you're over the ratioed amount of 50. I've run pumps which cycle the entire FT volume in 2-3 hours but I added supplemental aeration to the tank, so you can do likewise if you insist on your design.

thanks for the info Harold;i think i am going to put a little more pump because i have 6.5 &over on my oxygen also i found a small fry in the skimmer ,so that may have been the reason for my bad water quality.
