I am going to use the same filtration I had on the 900 gallon system.
Sump space is about 220 gallons (For now) a 55 gallon trashcan full of scrubbies, and an equal amount of fully submerged scrubbies in the sump. Bio-tower trashcan is run off a Reeflo Dart and the main circulation pump will be 1 (For now) maybe dual Reeflo hammerhead pumps running at about 4200 GPH.
