Ok so i've read that if you have a tank over 125 gal. it should cycle 3 to 4 times an hour. So if you have a 150 gal tank you should be flittering close to 600 gph.
If you have a 30 or 40 gal. sump filter do you add this to the caclulation? Which would make you water volume 180 or 190 gal and filtering volume 720 to 760 gph?
