Does anyone see a problem with this?

I will post pic when i get home from work but for now here it goes.

Tank 220

I have my 220 drilled is the rear 2 corners. 1" for overflow, 3/4" for return. I couldnt drill the bottom so i drilled the back. I have the bulkdeads installed. Coming off the bulkhead i have (1) 90- degree elbow facing upwards. then i have (2) 45 degress bringing the pipe back to the rear corner. The standpipe. (1) T with cap and for vent and (1) 90 off the horizontal part og the T facing downwards.

This quick drawing is awful but you should get the idea. So does anyone see anything wrong with having the 45's?

Looks like it will work to me.

As described/drawn… it will work…
　
When the pump is turned off the water will drain bottom of where the T meets the 90*…
　
If you put an extension on the 90* after the T, you could easily convert this design to pick up water/waste from the bottom of the tank without creating any additional risk of draining the tank…
　
I suspect this configuration will create a good bit of gulping noise which will come from the opening at the top of the T…

There is a cap on top of the T with a hole drilled in it.

Here are some actual shots. Sorry about the flash

This type of setup will work, just as long as your not trying to flow too much water through it. Your return pump would dictate how well it works, and as for the cap on the t, remember to start off with a smaller hole first since you can always increase the diameter to help with the siphon effect.

Any idea what the max GPH would be. I have dual overflows

You're looking at a max of about 600gph per overflow.

HUmnm Why would you go for extra work when the tank already have water in take system? In the long run there will be some fish waste remain at the bottom of the intake box.

you reinvented the dorso standpipe... congrats it should work great
