Was highly recommended by both Ben and Austin at the Woodthorpe store for us in a red sea reefer 350 tank. Havent used it yet as tank arriving in a couple of weeks from them. The recommended flow by red sea is 3000lph so this pump will probably run at just under half power. At 55 watts the power consumption is low to especially when the 55 watt is taken at full power of producing 6500lph flow. Really good price and the store had lots of time for me in making my decisions. Lincs aquatics Ben has been a great help to me and really helpful in explaining things to a newbie reefer.
