I had to go with a 180 gallon sumo and only run 8 inches of water in it, tank is 30 feet away 2 inch drain lines 30 feet long can hold a pile of water, plus the inch or so in the tank.
Could u consider changing the height of water in the tank using your drains, I can adjust mine so water is touching the euro race or take it to water just above the overflow slits.
