We generally recommend that on average, you turn over your aquarium volume four times per hour.

Moreover, how many GPH do I need for a 30 gallon reef tank?Recommended flow is 20 to 30 times per hour for soft and LPS corals, up to 50 time per hour for mixed reefs and 50+ times per hour for SPS dominant reefs.Also Know, how many GPH does a 29 gallon tank need? A good rule of thumb to follow is that a pump should have a flow rate of 5 GPH (gallons per hour) for every gallon of water in the aquarium. For example, if you have a 29-gallon aquarium you will need a pump with a flow rate of at least 145 GPH to effectively turnover the tank. Accordingly, how many GPH does a 40 gallon tank need? Well anyways, it is generally said a flow rate 5 times the amount of gallons your tank holds is good flow for a typical aquarium. So the 40 gallon x 5 turn over = 200 GPH flow rate. So you would want a filter/pump rated at 200GPH or more.How many GPH should my return pump be?For saltwater aquariums, the general rule is 5 times to 10 times turnover for the aquarium. So if you have a 50 gallon aquarium, you will want a return pump that is capable of delivering 250 GPH to 500 GPH back to your aquarium.
