I am currently trying to setup a 125 gallon FOWLR tank.
Only thing that i am sure of buy is a Vertex IN-180 protein skimmer. Haha i am planning to do a sump underneath of 40gallon long and idk how i need to set it up as in overflow box and what size overflow to get as well as return pumps to return the water back into the tank. I want to do a refugium inside the sump. Can any one help me out on what i should buy and how big i should get it? For example... I need powerheads. Should i get 2 powerheads rated for a 75 gallon that circulates 750gph or a 125gallon rated powerhead... and so on and so forth... thanks for all who help me out! -Taylor
