My fluval 13.5g evo cracked in a bad way. I think one of my colleagues bumped the return and cracked it. I caught it early and siliconed the cracks and stopped the leak but I dont think this will work long term. I've already bought a second 13.5g evo to replace it with but I have to drill it overnight at home... do you guys think the silicone will hold overnight? Good news is the plastic divider is holding the glass in place on the inside and not much weight pressure on the back panel of the glass.
