Also if i run a sump could I plumb 3 of the holes together the the left side of the tank for the overflow to the sump and use the one hole on the other end as a return? But if I do that I would have a water level just below the frame . Anyone have any ideas or suggestions? Thanks
I got the same deal & same problem from CL
only got 2 holes tho
Did you just put a sheet over the hole & used silicone to seal it?
That's what I was thinking of doing
