Possible Leak?

[Caliban]

Hi all! I have a 60 gallon freshwater tank that has had persistent water underneath it today. I don’t really know how old the tank is, as I got it used. I’m apprehensive to jump to conclusions, as it is fully stocked so resealing it would be a pain. It has reflooded itself about four times over the course of the day. I did do a water change this morning, so I’m wondering if it’s just residual water. If I do have to reseal it, I have another tank that can probably handle the extra stock. However, my angels do not get along so the my rainbow fish that are in the other tank.

My main questions are:
How long should I wait with it reflooding itself?
Should I be concerned if the water level ISNT dropping, as in mystery water?
How have people resealed tanks in the past, and how much time does it take?
Also, should I be concerned about overstocking my other 50 gallon?

Stocking of each tank goes as follows:
60 gallon:
2 angelfish
1 Bristlenose pleco
7 gold tetras
2 Cardinal tetras
5 Kuhli loaches
50 gallon:
1 bosmani rainbowfish
1 goldfish (moving to pond tomorrow)
2 hill stream loaches
5 harlequin rasboras
7 glow light rasboras
1 guppy

Thanks in advance,
Caliban

Find the drip area first. It might just be a micro Crack in the top rim, or it might be a seal. If it is a seal leak, it's probably better to buy a similar sized aquarium during Petco's half price sale.
I've never resealed a tank. I wouldn't trust my workmanship, Lol.
I've never heard anyone say that resealing a tank is easy.

Thank you! I’m probably going to see if it stops tonight, but I might buy a new tank. If I can find the source of the leak, if it exists, I’m probably going to try to fix it. We shall see!!!

If you do switch as I’m inclined to agree with A201, buy a big tote tub and set it up as a temporary holding tank while you switch out the old for new tank. I just did this with a 65g leaking tank and replaced it with a 55g in two or so hours. I never found the exact leak. No matter the cause, a leaking aquarium is always going to be replaced by me. All my tanks acquired used were used for reptiles and amphibians, terraria, or combinations. Interestingly, the leaking tank was bought new ten or so years ago.
Nothing makes me more uncomfortable than a leaking tank in the fish room……it truly gnaws away at me.And, the feeling of “no more leaking” is quite relaxing.
