[All4Cody]

So i was thinking about my pluming today and i think i need to drill bigger hole for bigger overflow. i have 2 1" now but i think i need 2 2"
my return pump i a reeflo BARRACUDA 4300 gph with 1 1/2 intake and outflow. i was going to drill a 2" bulkhead to feed the pump out of the sump and 2 2" into the sump is this going to work?. never have set up a tank like this ???
thanks bryan

Use 2" for the drain and use 1.5" for the pumps

you dont want your return pump line to be bigger than your drain or be able to pump more than you can drain because you will over flow your tank and have a nice pool of saltwater on the floor.
