Silicone strip released

[CanadaCat]

Wiping out my AIO 20g cube waterbox, a 6" long, thin rounded strip of black silicone floated up. It is the interior angle of the joint maybe where the glass meets the filtration wall, I think, not the interior glass-to-glass seam, but I didn't see its origin. Is there a safe way to repair? There is no leak AS OF NOW. I am just worried about a potential tank failure. Tank is only 5 years old and on a waterbox stand. Would you drain the tank and reinforce-silicone? How long to cure before putting fish, rocks and coral back in?

Do you know exactly where the silicone came from? — if it’s from the AIO divider, it’s less important… if it’s from a structural seam, it’s more of a worry!

If this silicone is from one of the structural seams, you can drain and clean the tank prior to applying a new bead of silicone over the area, then waiting 7 days for it to fully cure!

What do you recommend putting the water, rock, coral and fish into? Is a rubbermaid container strong enough to not warp/fail?

Hopefully it's just excess from the seams that isn't really critical. I think it's called flash but not sure. I've had quite a few off the shelf rimmed tanks have had that excess start to peel and I just trim it with a razor blade.

Yep, any Rubbermaid product I’ve used will happily hold water, despite some bowing a bit!

Remarkably, even those yellow lidded black storage bins from the big box hardware stores are capable of holding water, at least for few months, before they start to fail!

That tank is only $290 brand new. If you are really concerned, I would just order a new one and just sell, give or throw away the current one. They offer extended warranties for a little extra cost as well if you have any silicone issues, concerns, etc in the future.
