Leak in top corner, need some help/advice

[jawz]

Alrigtht i bought my 35 gallon used and it had been sealed by the looks of it, now its been oh like 6-7 months ive had it and i have a leak in the top back corner. Its small because over night i lost maybe 2 litres of water. It like drizzles down, i kno its at the top because i drained some water and about half inche or so down it doesnt leak anymore. I dont have another tank to move this fish or what not, could i patch it with fish still in the tank? and just let the water level remain sorta low while it cures? or would the evaporating water affect it too much? IF this is totally wrong, could someone plz advise me what to do. I am willing to buy a whole new tank if neccessary but it is a small leak.

If you bought it new, I'd sure check on a warrenty. Might be able to use an epoxy. It cures under water.

no ive had the tank for 6-7 months after i bought it USED so it has some years on it.
What kind of epoxy?

all-glass aquarium makes silicon for tanks but a epoxy would be super strong and better then the all-glass silicon

hmm what type of epoxy is safe for fish tanks?
also do i need to drain my tank or could i do it with a lowered water level for a while?

I would use silicon and keep the water level down until the silicon cures.

hmm thanx richard, i called the guy at Big Als, which is local to me and he said id have to tear the tank down and remove the old silicon and reseal it

I would get a price on a new tank. Its going to be a little more work to switch the tanks, but I think you would be better off down the road. If you bought the tank used it has a few years of use on it, its already sprang one leak you have the chance of it leaking in the same place if not properly sealed or have another leak come up in the future. Just my .02 good luck on what ever you decide.

hmm well a new tank, same size costs $55 with taxes CND
all glass silicon around $15 CND

Yeah.....I'm just throwing some ideas out there. If you go with a new tank you have piece of mind that seals will be good and hold for many years to come. Its not a guarantee, I've seen brand new tanks with faulty seals, but I think you run a greater risk resealing it. It may leak in the same place that you patch or it might spring another leak somewhere else. If you looking to keep this same tank set-up for awhile I would personally look at replacing the tank itself. IME every tank that I have to reseal it sprung the leak in the same place, it might have been because there wasn't enough epoxy on it, I don't really know. But every tank that I tried to fix I just went ahead and replaced soon afterwards because of the reoccurring leaks.
