I just picked up a 210 7x2x2 that I am sure is drilled for salt water but I want to use it for fresh. Each side has 3 holes. 2 toward the top of the back glass and one on the lower part of the back glass. They also gave me two pumps one is very large and the other is smaller. I plan on using a 75 gal sump and my FX5 for back up. What will be the best way to plumb this tank. I have had alot of tanks but never a drilled one. So this is a learning curve for me.

Yes pictures would help, but some of the holes were probably used for a Closed loop system for circulation. This will help keep debri moving to be filtered. Depending on your stocking it could be too much flow.
Hard to say what the best way to plumb it is. You can just cap off the bulk heads if you want.
They probably had the bottom holes connected to the small pump for extra circulation. Then maybe two of the top holes for over flows, and two for returns so they can be pointed in different directions for fo choatic flow, good for salt water.

Yeah I am sure it was a salt water tank. Here is a pic the previous owner had of the back of the tank.
So you could just plub it like they had it and see if the current is too much for your stocking.
How much gph are the pumps?

So another pump goes from the sump to one of those other pipes on the top 2 holes?
