Will this overflow work?

Well I got everything hooked up and it's working great. Made a few design changes though. Instead of drilling a hole near the top and running a pvc pipe to the bottom, I just drilled a hole near the bottom and connected the pipe from there.

Thanks for all the help!

GraphicGr8s It is still basically a siphon. It is made so that it will stop when water level reaches the tee.
The OP said he could drill the tub since it was plastic. Why go through all the extra hassle and worry about losing the siphon if you don't have to? And he doesn't have to.

I mean look at the design of the straight overflow. 2 elbows and pipe. Pretty simple and no worries about losing siphon.

Not soley, it's a constant overflow siphon. The 'T' that goes up is exposed to air so yes the inlet is siphoning, but then it falls over the 'U' as an overflow internally. Several people in my club use them and they work great and are a great way to reduce noise and CO2 loss.

Look at the second and third pictures. The red portion is not protruding into the tank water so that part is open. You can also just put a cap with a hole at that spot, but using the elbow allows you to hang it on the tank nicely.

Yep. Your correct. In fact so long as that pipe is open to the atmosphere he could run the pipe totally submerged and not worry about overflowing the "tank" or siphoning if power goes out. I've just found that even submerged it doesn't always flow 100% 100% of the time. It takes patience to get it balanced correctly and consistently.

Now someone will come along and say they've gotten it to work and it was easy peasy. And it really is. It's the "consistently" part that makes it a bit harder. But it is fully doable

I've actually tries that style overflow from uarujoey on my indoor aquaponics system. Works really good, nice and quiet.

But I switch to this, much more simple and I can run a bit of mechanical filtration.

Thanks for all the help Graphic! Still debating on what type of overflow I want to use. I did notice that after trying out the 2 styles of overflows on my indoor system, the one from Uarujoey did seem to flow just a bit better. But the style that I'm currently using still handles the flow well and I can see some mulm being sucked from the bottom of the tank.

Tetrameck I think a better idea is to get a strong circulation pump, put it on a timer, aim it along the bottom and have it stir up the tank a few times a day. Maybe even have one on each end of the tank and put them on alternating "aggitation" schedules. Most the gunk will get pushed into the water column and sucked in your canister intake.

The first diagram is basically a due so style set up and the water sat at about 3/4 of the pipe and drains till the bottom of the horizontal section works very well nice and quiet

GraphicGr8s Kado your overflow will work just fine. You just have to match inflow to outflow carefully. You also need to make sure that the pipe you have going up is always open to the atmosphere or you'll have an efficient siphon and water in the sump and on the floor instead of in the tub. Only thing I'd suggest is to put your tee on the pipe going to the sump. The tee ill be resting on its "side" Less connections that way.

Drilling the bottom of the tank will definitely give you the results you're looking for without the need for all those contraptions. Plus it'll look nicer.

lol, that's my back up plan already got an extra canister filter ready. Just thought that this tank being outside the extra water from the sump will help keep the water temps a little more stable.

edit: I'm thinking about running the sump inside the house so I don't have to worry about electrical stuff outside. Don't know why, but there are already some nice holes in the wall that are the perfect size to run PVC pipes.
