[kathouqc]

Hi, I just bought a 240G and I want to make it able to filter with a 90G sump.

The aquarium size is: 72x32x24

Both big hole on each side is at 6" from the side panel, and both hole are drill at 2 1/4".

Has I bought use, what I can do for a filtration with a sump with these two hole?

I want a least 2000Gph

Based on the hole size that’s likely a 1-1/2 schedule 40 bulkhead. Measure in mm and be sure to get a good measurement to be certain.

You say this is acrylic tank, then I would drill it for a large overflow box and use those two holes for returns.
