I'm setting up a 180 gallon reef display on the main floor and my sump in the basement
Have a Reeflo Hammerhead/Barracuda Gold pump for my return (about 2800 GPH at 12' head)
The overflow has 2 - 1" drains in the center overflow and I want to do a herbie overflow.
My question is, with that big of a pump and I'm shooting for close to 10x turnover as I can, I'll have a gate valve on my return pump, is there a need for a gate valve on one of the drains still?
My guess is I'll probably tune the return pump so the main drain line is running wide open as a full siphon and just adjust the gate on the return to achieve this rather than adjust a gate on the drain but I'm not sure what a full siphon 1" at 12' can handle.
Does that sound like it will work without needing a gate on the drain?
I found a chart showing siphon flow rates but was looking at 12" drop being 1250 GPH for a 1" PVC.... and I'm looking at 12' drop instead. Will I need a gate valve on that drain as it would move a lot more than 10x water? If I'm at 2,000 - 2,200 GPH I would be fine with that.
any feedback would be much appreciated
