hi all about a year and a half ago i built a 120 gallon plywood tank with three viewing windows made from 1/2 inch acrylic. well 2 months ago my house suffered a fire and i had to drain the tank and it went off to a cleaning company to get cleaned and then we will get delivered back to me when my house is fixed. i can almost positive that i will need to reseal the tank because im sure the acrylic will pop out from being moved. also i need to replace the back plywood due to water damage from my multiple overflow designs. so i am thinking about replacing the acrylic with glass because i really dont like the acrylic its not bad but it already has some scratches on it and it was a bear to seal and i had to reseal it when i moved it from the garage to the house. so since i am planning on replacing the windows, and replacing the back. do you think i should just rebuild the whole tank or just try to fix this one? im afraid that i will end up destroying the tank if i try to replace the back panel because it is glued, screwed every inch, and is fiber-glassed in. also i dont know how hard it would be to remove all the silicon that is currently holding in the acrylic. so if you were in my shoes what would you do. here is a pic of the tank shortly after finishing.
