Or I guess a better question would be can I put a band aid on this for now? I know the proper way to fix it is to replace the side panel but can I put a short term fix on this with a couple pieces of glass siliconed in place? There is almost no pressure on the pane because it is the return section of the sump, on the other hand it seems silly to risk the pane breaking while I am gone and draining my tank. Any opinions?
