300 gph

  1. General Reef Discussion
    Does 300 gph of filtration in a 75 gallon tank via a 29 gallon sump sound sufficient?
  2. Reefing Equipment
    I have a 36 gallon bowfront and i have decided to put in a 10 gallon sump. I have a 300 gph overflow box and am wondering what size return pump I should go with. I know that it has to be larger than 300 but I'm not sure HOW much. The pump will be around 4 ft below the top of my display tank...
