Fluval edge custom overflow

Ok so not sure if this is in the right section but here is my idea.

I have a fluval edge i want to use as a frag tank, my idea is to drill 2 holes into the top section of the tank, it is just acrylic around the opening so this should be pretty simple. I made up a simple drawing in paint. This is going to be plumbed into my 75 gallon DT with 30 gallon sump, and i am going to just T off the return pump with a ball valve to control flow.

After drilling w.e size i decide, most likely 1/4 in pvc, the overflow will just be a piece that comes in, goes down under the water about an inch, and is capped off. Then i will just drill a lot of small holes in the pvc to allow it to siphon water out. (i know it wont surface skim like this, but its a bare bottom, with lots of flow)
The return will be plumbed into the 1" return line going to my DT with a ball valve so that i can adjust the gph to how ever much my overflow can take.

sorry the pic is so crude.

What does everyone think? any ideas? or tips?

 

Very cool! Looking forward to seeing this project complete.

 

ugh i hate being busy on nights i come up with these ideas! i can never get to the hardware store when i want to!:

do they make a T that goes from 1" in to 1" out with a 1/4" out? lol

is 1/4 to small? i mean its only a 6 gallon tank... how big of pvc should i use?

how many gph should i be looking to get for a 6gal tank?

 

Well like you said its only 6 gallons... So there really doesn't need to be a lot of flow going through the pipes..

I tried to make a overflow with 3/4 and it would choke at 500 gph so I was forced to do 1in. But I don't think you will need 500gph in 6 gallons.

 

They do make that tee. If youu can't find it you could try using bushings.
