What type of pump are you using? You are most likely correct in you're going to be dealing with quite a bit of flow loss, certainly bringing you down below your overflows rated capacity.

Honestly with a few elbows, a T fitting and reducing to 3/4" outlets you're probably maxed out at 800 orso GPH. Add a reactor or two and you're into the 5-600 GPH making it to your outlets. Split that in half and you're 250-300 coming out of each one.

I had to look up the performance curve on your pump cause I wasn’t sure. I don’t run any DC pumps. Don’t know how high your display tank will be, but at 6ft of head pressure, it puts out around 800gph. I’m thinking you want to return through 2- 3/4” bulkheads drilled through the top back of the back glass. This will work fine with minimal reduction vs. going with 1- 1” bulkhead into the display, which would give you the 800gph without a nozzle. 2 -1” bulkheads will have to be reduced to 2-3/4” male loc-tite threads anyway. So if you reduce before the 3/4”bulkheads or down below at the 1”x3/4”x3/4” T,the difference in loss is minimal. I would go with 3/4” inside thread bulkheads, connect to 3/4” loc-tite male adapter, connect a loc-tite 3/4”x1/2”x1/2” wye, and then finish with 2-1/2” nozzles on each side of the tank.

thanks for the advice, just wanted to Clarify on returns, 1st time building a tank with sump want to make sure it’s done right
