Does this overflow system works as it meant to be?

[benn371]

Hey All,

This is embarrassing for me to ask this here to all you Gurus out there but still, me being a learner as well as being budget cautious have to take one step at a time, attached is the diagram for a 120g tank drilled in the lower end of the tank for overflow system to the sump, when the water level falls below the level of the T-Fittings the overflow should stop, and with a vent on the T-Fitting I hope there wouldn't be any siphon as they act as a siphon break, so when the water goes equal or above the T-Fitting the overflow system should start working again all by itself.

Please help me here whether I'm missing something here or is there any changes to be made in this.

thank you.

You chose dangerous way of "overflow" - if there starts leaking at drill point, you will have almost all water on the room floor..

I would rather suggest 3 hole system in overflow box - if it leaks, only water in overflow box will leak, not entire tank

If your tank is drilled at the bottom like that it would (IMO) be far easier to silicone in a glass weir (assuming your tank is glass) to create an overflow to control the level of water in the tank. That way you remove the risk of draining your tank with a plumbing leak, and the pipe coming out the back can go straight to the sump.

I was actually searching for an overflow that would get waste from the bottom of the tank for my RES turtles. Not sure how effective it is though. No surface skimming but turtle food floats anyway so it's doesn't matter to me. Called a solid lift overflow. If anyone have any experience with it and can share info that would be great because I couldn't find much on it.

Looks like this pic I found.

I've done that on a few tanks, a like the results. If you want to get surface skimming just use a cut off wheel and cut some vertical slots in the upper section. This is how my turtle tank overflows are, sucks up large waste off the bottom and skims the surface film away.

Yes, this is a glass tank and I'm planning on 3 1.5 Inch pipes and the bulkheads are silicone glued in the glass to avoid any possible leaks. I'm sure this way it works great right.
