I recently bought a new 55 gallon, RR, AGA tank with the corner overflow. It has a one inch bulkhead for the drain and a three quarter inch bulkhead for the return. Can someone tell me what the amount of flow is suppose to be rated at? I currently have a mag 7 hooked up for the return from the sump, and while I have not overflowed the tank, I am a little nervous about it. The Mag7 is wide open with no relief to the sump and is on 3/4 inch hose. According to the head loss calculator I have about 450 gallons of flow returning to the main tank. Any advice is appreciated.
thanks
