Water started gushing from the top 5 inches of my tank tonite. I immediately shut off the sump pump to lower the level of water and drained 15 gallons out to lower it more. The leak stopped, so it's only at the top 5 inches. I wrapped two ratchet straps around the whole tank to give support. There are 2 circulation pumps working to keep everyone alive while I repair the seam. I scraped the old silicone from the seam about 6 inches down. I'll clean it with acetone tomorrow and apply a fresh bead of silicone and let it dry for 2 days. Does this sound like it'll work? Any advice is appreciated.
