So I would like to increase my flow in my tank. I have a reeflo hammerhead/barracuda return pump thats dialed way down, maybe 35%-40% of its full capacity but my refugium can't handle the drainage coming from my main displays. The refugium is a repurposed 75g tank and i have a full siphon and an emergency drain. Underneath (not seen) is a 100g rubbermaid trough with my skimmer. I need to do some plumbing upgrades so I can crank up my pump! So here I am picking away at your brains on a sunday morning!!!! Don't mind the messy wiring as I'm always tinkering and trying to figure out "better" ways to do things!
I snapped some pics to show how the flow goes. I have gate valves to control siphon on all 3 drains (2x220g & 1x60g) that drain to a 75g fuge, then drains to a 100g sump. My emergency overflows are connected to 1-1/2 line. the return line is a 1-1/2 that manifolds off to 3- 1" lines.
