Id have to agree with others on this one... could last 10 more yrs...could leak in 10min. all part of the game we play. Since its in ur livingroom and if u have another tank /tub to put ur fish in, it can be resealed and ready to go in a cple weeks time. Reach in and stick ur finger in it lol... ull know right away if itell pull off. if so, drain er down for a reseal. i once resealed a 265 for a friend over an hr away. Can be stripped, cleaned and re chaulked in a few hrs time. I like to let them cure for 7-12 days.
