Similarly one may ask, how much flow does a reef tank need?The minimum recommended turnover rate for a FOWLR aquarium is between 10 and 20 times per hour. If you have a 50 gallon aquarium, you should aim to have at least 500 to 1,000 gallons per hour of flow. Though you may be able to get away with 10 times turnover, we strongly encourage you to aim for 20 times turnover.Secondly, 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. Also, how much flow does a 75 gallon reef need? Ecotech recommends 1600 to 2600 gph for a 75 gallon tank.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.
