![]() With 1 inch diameter pipe, the maximum flow will be around 2000gph. I have assumed that the vertical difference between the water level in the overflow and the water level in the sump is 3 feet ( the pipe runs to just bellow the sump water level in a Bean setup). OK, I'll start with the Bean Overflow, specifically the full siphon drain as this is a limiting part. ![]() ![]() Please provide accurate measurements if you can. Would the reduced overflow area cause big problems? If the intake to the CL pump is 1" should my intake bulkhead also be 1" or larger, with a step down coupler at the pump?įinally, if I can get a local vendor to 'notch' the rear pane I could drill the return lines a bit higher and clean up the entire back pane with this implementation below. Will the horizontal overflow be capable of handling all this water without being extremely loud? Would I be better off drilling a different hole for the closed loop intake in the bottom of the tank? Will 1" drains suffice for BA overflow system running around 1000gph after head loss? The excess flow from the pump will be routed through a bypass to return CL5 on the back center of the tank, which will provide constant flow. 1-4 (labeled below) will be fed through an ocean motion's squirt powered by a Pan World 100PX-X 1270gph 13'. The return pump I envision using will be a Quiet One 4000 Flow (Rate: 1017 gph)Ĭlosed loop will provide ALL other water circulation in the tank with 5 envisioned return points. This will mitigate the problems associated with backflow from a power-loss. I am going to drill the returns below the overflow box and use loc-line to raise them towards the surface and use flare nozzles solely for surface agitation. I plan on adding a small strip of acrylic teeth so I imagine I could adjust this to change the water level. I am building the tank myself and am wondering how much shorter the rear panel should be to keep the water line ~.75-1" from the top of the tank. I am wanting a quiet system, but the slow trickle of water into the overflow box will be allowable if it isn't a 'rushing' sound. I know many people have troubles with strainer intakes in the tank and I am wanting to incorporate an external calflo overflow along the rear panel and a beananimal overflow system. I need some help with the overflow and closed loop system I wish to implement and am open to all ideas and criticism. Not so nano but I figured many of you could help on this one:
