How to seal a drilled plex aquarium?
I drilled two 1.5 inch holes in each corner of my 100 gallon acrylic tank to accept the bulkhead fittings. I am now choosing to not use them and the sump and want to go with a canister filter (long story) instead.
What would be the best method to seal the bulkhead cutouts? I could either install the bulkheads and cap them from the back or....should I go to a plex shop and install (weld) a small round or square piece on both sides to cover the holes?
I have a nice 3d background so either way it will not be visible, I just want the best leakproof solution.
