How do I pull this off? Preferably no siphon so I don't accidentally drain the tank onto the floor when my room inevitably has a power outage. I have a 40 that I want to hook up to a 10 gallon.

Your only safe option is an overhead sump. HOB overflows have the inherent risk of breaking siphon. There are precautions that can be taken, such as an airlifter pump, to remove the air bubbles that tend to gather in the top of the siphon tube, but you are depending on that pump to always work. If the siphon breaks, all the water in the sump is pumped into the display tank, risking an overflow and burned out pump. Nothing is absolutely foolproof, but with an overhead sump, all you are depending on is gravity, which has a pretty good track record of consistently working over the millennia. Power goes off, pump quits - you're still good

Gotcha, don't know why I never thought of the sump getting pumped into the main tank. Always thought it would be the main tank overflowing the sump.

Sassafras Sassafras said it first. Only safe way for this to work is with a hang on overflow in an overhead sump configuration. Ironically this is the only way to safely use a hang on overflow imo since there is always a flood risk otherwise.

I agree with the overhead sump, though you might have to rethink your 10g idea, as it will need drilling if you want to get away from any form of syphon in the system.

A quite popular way of doing an overhead sump is to use one of those long garden planters. There are some basic videos on you tube.

A small hidden pump in the display tank pumps water up to the planter. It flows in one end, goes through mechanical and bio filtration and flows down into the display tank via gravity through a hole in the bottom of the other end of the planter.

A power outage won't cause you any problems whatsoever regarding overspills/flooding.

PVC overflow as per King of DIY on YouTube, but the second design where the main intake pipe is set within a wider pipe that acts as a weir.

I use them and the siphon stops as soon as the water level is below the top of the weir pipe, but doesn't need to be primed again when the water level is topped up. It just restarts automatically.

Overflow box. Spend the extra money for eshopps or equiv over the dyi
