A pump (or powerhead) moves water at X gallons per hour - thats flow.
Depending on whats in your tank, you should turn the water over 10-30 (or more!) times per hour
So if you have a 50 gallon tank you would need 500 to 1500 total gallons per hour of flow to achieve the 'ideal' turnover.

Flow usually measured in gal/hr on a meter inline with plumbing fixture.
Tells you at what rate fluid is moving in a pipe!
Turnover is how many times an hour the total volume of water in your tank is replaced. Example let's just say a 90 gallon display tank with an overflow.
Everything is happening in sump (filtration). Water in main tank is moved by return pump (quiet one 4000 rated at 1017 g/h) and 3 maxijet 1200's (295 g/h). Anything in the sump for pumps and filtration we don't count as it is taking place in the sump. In the main you have the return and 3 PH's.
(1017 + 295 + 295 + 295) = 1902 g/h total at company rated specs. I use 75% of that number and find it's fairly accurate. So total is actually 1427 g/h. Take the actual flow or water movement (1427) and divide by the tanks volume (90) = 15.86 X per hour turnover.
It may sound a little complicated but it really is just math. Add up all water moving parts in the main tank and then find a factor that makes it real instead of manufacturer rating (ie 75%) and divide by tanks volume. Hope this helps!

Thanks that was what I was looking for, Man I can remember when I first started this hobbie there was hardley any of this, need this much flow, need this much filteration, need to use ro water. man I wish it was like that again.
