got two tanks, and I heard refugm/ or sump is better? I want one for my 75gl. reef but dont know anything about them! I dont even know if a sump or refugm are the same or what? They are expensive, so I was trying to see if there are any drawings or blueprints out there to help me realize what they actually DO! and how are they built? PRETTY PLEASE! Let me in your DATA for sump/refugm building.
