i appear to have cracked in the process of moving it back inside after the reflooring of my house. all the cracks are confined to one pane, but it leaks pretty bad, my question is how should i repair this? is is as simple as getting a large piece of acrylic and siliconing it over the existing panel and redrilling the hole for the bulkhead, or should i just replace that panel (also can that be done without complete disassembly?), or should i just bite the bullet and get a new sump?
