I am planning a 375 gallon (96x30x30) tank build. I want to set this up this tank using the Triton Method. Based on this tank size, after adding 400-lbs of rock, 2-inch sand bed; I will have approximately 250 gallons of water in the tank. If my calculations are correct then I will be need a 40-50-gallon refugium in the sump. It appears that only way that I am going to find a sump with that large of a refugium is to have one custom built? Before that start on the journey of finding custom sump builder, any advice on the overall dimensions that I will need in the sump, the size of the other compartments and what other features I should ask for in the sump. Does anyone have a design for a Triton sump that will work; the sump will go under the tank?
