It's a home made plywood tank. I'll have to put another coat of fibreglass on it. If I move some fish around, I can free up a second 55. Another issue is that my 55's don't have lids. Darn giant danios like to jump out.
Silicone should be left to cure for a week in normal temperatures.
So sorry you're suffering the unique pain of a leak. Nothing can top it for suckiness. Good luck with drying the carpet. Can you pull it up to make sure all underlay and backing is dry? And, of course, best of luck to the fish. They'll be fine, I'm sure!
Edit: cichlid said it was fiberglass, sorry! Not sure what the cure time is on that. ignore me, lol.
