Pump Head Loss Measurement-
How to measure how much flow is in the tank. Very important to understand head pressure as what is advertised for the GPH measured right from the pump, with no pressure.

Please know, filters will lots of media will dramatically reduce flow. This specially is true for Canister Filters, HOB with media, Intakes with sponges. etc.
Pumps placed below the aquarium will also affect GPH. Many pump will note GPH at a certain distance.
Different pumps are better to handle Head Pressure at the same watts, simply by design. Some operate very poorly when pressure is added.
Combined Suggested Aquarium Turnover Rates (per hours):
Fresh
5 times for an average non-planted freshwater aquarium
2-5 times for an average planted freshwater aquarium
2-3 times Betta or Fish Fry Grow-Out aquariums
6-10 times for high bio load aquarium such as a "Monster Fish" aquarium- Also for packed planted aquarium for algae control.

Marine
8-10 times for an average fish only aquarium
10-12 times for an average FOWLR or very basic reef tank (FOWLR = Fish only with live rock)
14-20 times for an Advanced Reef Tank
With Acropora and Montipora coral, which are often at the top of the reef, these can require as high as 40-50 times per hour combined circulation!
DO NOT make the incorrect assumption that the wave activity at the top of the reef means corals, anemones, etc that live in more protected areas of the reef need the same flow rates as Acropora and Montipora corals.
