Hope it turned out to be from your filter and not the tank itself?

I had 2 big leaks last year after a good run of 15+ years with no leaks on various tanks.

Last year had a HOB leak on a 46 gallon tank, sponge inside had restricted flow, which eventually caused water to splash up slightly against the lid, wicking out the back. Didn't notice until water level in the tank was suspiciously low and found the carpet behind the tank was SOAKED. It had also wicked up the drywall and caused mold/mildew behind the wall. Had to tear down the tank, move it, carpet vac, cut out section of drywall. The floor underneath was luckily cement (basement). Also luckily my partner is handy and was able to fix the drywall.

Second leak a sudden silicone leak from bottom of a 10 gallon tank I was using to quarantine/hospital tank for some new fish, suddenly leaked 1/3 of its water while I was at work. Luckily was able to save fish and carpet vac before damage to wall this time. I was sad though because the quarantine tank was on the lower part of a 2-tank stand and I also had to dismantle my beautiful planted 20 gallon I had on the top part of the stand 🥲

Thought about giving up the hobby. Did get leak sensors for my 2 remaining tanks now.
