yes i need to see one. however in my 125 i have only 2 pumps the mag7 for a retun split in two returns at opposite ends and a 1000 gph pump in the tank and my flow is quite dramatic in there. i did a little reconfiguring of my elbows and such and now i had to lower the water level in the tank as when the waves colide in the middle it was jumping out of the tank.
