im in the process of setting up a 210 gal reef. the tank flow rate has a max rate of 1200 g/ph which only allows for a max turnover of about 6 times per hour....my question is what is a average amount of times to turn a tank over per hour ,also the pump i bought for it with turn it over about 4.5 times per hour i think 4.5 times per hour is sufficent ,like to get some oppinions on this thanks
