Tank Repair

[vieiras]

We noticed our tank sealant has formed a space. it has not make it way all the way to the edge, but worried it will soon. Anyone have ideas how to repair it? We have a Waterbox 130g tank and just bought new fish, so can't handle that heartbreak.

In my opinion it will have to come apart and be cleaned of all residue and recaulked with aquarium silicone
