Ok, I need a little help. I have a 150 gallon acryllic tank, where one of the bulkheads sits on the bottom of the tank I have a crack, I goes in 3 different directions. The cracks are 4"-6" long, I clamped them and got acryllic cement from TAP plastic. Glued them and let them set up, seems strong. My question is should I just fill it? will it hold? or should I cut a piece of acryllic 12"x12" and bond it over the top of cracks for extra support? Any help would be great.
