I don't think my tank lid is 'air tight' but when I'm home (and paying attention) I do open the lid up and let it get air so the tank can 'breathe', I think it helps my floating plants. I lower my water level about 3 or 4 inches to also prevent escapes further. I think in a 75 gallon you should easily be able to do that without sacrificing much water volume.
I too have had escapes, I was fortunate enough to find him hiding under my lazyboy.. lol (having hard wood floors helped too I think).
I really recommend a canister filter because intake/outtake tubes don't leave many gaps in your lid, HOB filters tend to leave avenues of escape all over the place..
