IMO, 1/4 inch is too thin for 75 gallon unless you have a very good external brace on your tank. Already tried assembling 50 gals using 1/4 inch and lumubo ung middle part ng tank, luckily for me hindi tuluyang nabasag. So i just placed two chambers in the middle para hndi masayang ung tank. ginawa ko na lang oversized sump and QT tank. If I were you I would settle for atleast the minimum is 3/8 or mas ok if 1/2 in.
