What type of DIY overflow for 75g standard?

[shovelrider]

I am upgrading tanks and it is time to drill the 75. I cant decide on the type of overflow. I know I at least want 2 holes, 1 for main full siphon and one for emergency. My question is: Where should the box go (left side, right side, or middle) or should I just do a coast 2 coast?

I currently run a DIY with 2 holes and an internal glass box that is only about 9'' wide. It sheets the water really thin and works well for the 45g.

current overflow:

New tank:

I'd do the exact same thing you did there for your 45g, which looks by the way, Fantastic!!. But going up a bit bigger, you may want 2 overflow holes and 2 returns, might want more flow going through the Sump.
BeanAnimal Overflow
Herbie Overflow
Are recommended, I like the Coast to Coast personally.

I went bean animal with a coast to coast. The only issue I've had is sometimes my fish will take a ride into the sump. I went with a smooth over flow, I should've added teeth.

Can you post a pic of that bad boy? (overflow)

The tank is laying on it's back here after I siliconed the over flow in. You can see the 3 drain holes for beananimal. My return comes over the top.

I use gutter guard to keep my fish and snails out of the overflow. I love toothless boxes for looks and how quiet they are.

Very nice LukeG. Very nice! As ShovelRider suggests, I've heard of people using the gutter guard before.

 

[LukeG]

Good suggestion. I'll look into gutter guard.

Looking good!

Go with an internal weir (overflow) and the BeanAnimal drain system. You'll be happy you did.

Your overflow box only needs to be 24" wide at max. That's more than enough linear overflow.

I went to modify my 75 and drill for the plumbing, the bottom had no indications or tags saying do not drill
I got started and BANG!
I was ****** but it made me buy a 220
Looks like your already in better shape than I was
Your on the right track
I have 2 toothed weirs in the corners and they are silent
My noise came from the water returning into the sump which after playing around with it I fixed by running the return lines right into the water as opposed to the top of the sump which had a 4" drop

Sucks that your tank busted but it looks like you came out on top anyway.
