Patch or reseal?

[jandb]

I was lucky enough to get some free commercial DAS setups several years back. They’ve been fine with no troubles until the other day. I had been running one bare bottom then added sand. A couple of weeks later I noticed I was topping it off more. Then it started leaking like crazy. The ~70 gallons would have drained in less than 2 hours. I noticed along the back wall there are 2 gouges. Do you think I could get by with patching the gouges and putting a light coating of silicone over the rest? I’m terrible at caulking and am not up for the project of pulling all the seams and starting over.

Any thoughts?

Post some pictures. But I can tell you putting fresh silicone over the old silicone isn’t the right way to do it. Resealing a tank might seem over your head but trust me it’s a job anybody can do. The hard part is scraping off the old silicone, the easy part it’s taping off some lines and running a thick bead down it and smoothing it out with your finger.
