I need some advice on how to make an external overflow box reliable -prevent flooding please:
I just started setting up a 65 gallon standard tank with no internal overflow. I had initially decided to use a hang on filter, skimmer...etc... but once I had the tank running that quickly went out the window! -now I just bought a Trigger Systems Saphire 26 sump, a Reef Octopus Classic 110 Skimmer and a Marine Depot 800GPH Hang on back overflow box with a Sicce 3.0 Return pump(rated at about 600GPH @3ft distance from sump to outlet return nozzle.) So the pump is rated less GPH than the return and seems a safe choice.
Ok... Here is what I have learned about making External Overflow boxes safe but I need some oversight: 1) Drill holes in your display tank return nozzle just under the waterline to prevent any back siphon from the display tank back into the sump through the display tank return nozzle should the return pump die. 2) Sump water level should have reserve space: Keep the waterlevel in your sump low enough to hold a volume of water from the display tank equal to the volume of water in both return and drain lines plus the level of water above the overflow box on the surface of the display tank in case system shuts down and all plumbing drains into sump. 3) Keep the hang on back overflow box intake box low enough below the surface of the display tank waterline so that air bubbles dont flow over and gather in the U siphon tube and break the overflow siphon causing your return pump to continually flood the display tank. 4) to further prevent the sump return pump overflowing the display tank, keep the water level in the Return Pump section of the sump low enough that your display tank can hold the additional volume of Return Pump Section of your sump.
Is this a full proof plan? Any advice and guidance is greatly appreciated.

all this filtration, heating..etc... is coming out to be replaced by the sump system
