I decided to return the weir and ordered in a eshops eclipse, that way I only have to drill one hole and I can save some space in the tank while having a Herbie overflow. Thanks for the suggestions.

Fishmanmike01, I already purchased the tank/stand/weir/ and bulkheads so ill probably stick with my current tank.

Acropora, I will try to size everything up. The single bulkhead i purchased is a bit of a monster with about 2" ID and a 2.5" recommended hole size. It looks like i might be able to get two 1"ID 1.5 inch hole sized bulkheads in there however they would need a 90° bend to point up because everything is coming in through the rear glass. Would this bend effect the herbie system?

Any suggestion on bulkhead size if i were to try to fit two for a herbie in the weir i have?

I have a Oceanic 57 i am starting to prep for saltwater and have a few questions along with some gear to trade.

Overflow:

I  will be drilling the tank for both overflow and returns, i have picked up a 7"h x 5"d x 5.5"w weir and am planning on doing a durso style overflow setup with a 1.5" bulkhead and two 3/4" returns. I should have enough room for a 90° street to get the downward facing intake. Should this stay relatively quiet? I am planning on a flow rate around 5-700 GPH.

Gear:

I have an acrylic 20lx16hx10d sump that i would like to trade for a 20l so that i can build a sump with a refugium

I also have a HOB overflow up for grabs.

Any advice on the overflow setup would be appreciated.

Thanks
