Hello, I bought a fish tank recently, and it's leaking badly, so I need to reseal it. I have some questions. Do I need to remove every bit of silicone? I've removed most of it, but there's still some stubborn residue. Will the tank not succeed if I don't get all the residue? How much silicone do I need? It's a 45 gallon tank, 36 inches long, 12 inches wide, and 24 inches tall. How long should I wait before moving the fish tank?
