aquarium seam?

what do you think of this seam? this tank is a 300 gallon glass aquarium and is probably 7 years old. it is a used tank and is currently sitting empty. will this tank have an issue down the road leaking?

If I am seeing the picture correctly, the second picture has me concerned. It looks like there is less than 1/8 of an inch of bonded silicone in some spots.
 
Water, movement, and time have gotten to the seam: it has air/water in it. Time to consider repair or replacement before it starts leaking/comes apart.

lol"¦300g isn't going to leak"¦well it might for the first minute or two"¦i would tend to think 300g is going to fail catastrophically though, that is a butt load of water/ pressure/ and weight

disassembling, properly cleaning and reassembling a tank of this magnitude will be likely as expensive as having it made in the first place"¦i am willing to bet a good couple thousand"¦.doing it yourself"¦considerably cheaper, yet very painstaking and time consuming...

Well at least you can appreciate the subtley... ;)
 
As for years, I have a 55 gal that was built in 1988 still holding water, although its not a 300gal.

I have been wondering the same on my 180 gal.
 
Yeah I had a feeling it would be something like that. After reading about how much effort and time it takes to reseal it, would it be worth it just to go for a new tank? There's a fish store about 30min away that said they would reseal it.

Yikes! I'm afraid to leak test it now. The tank is very well braced on the top and bottom, so could that possibly prevent a the tank from bursting?

If you've already been told that the seal is failing I'm not sure what you'll gain by leak testing it. Even if it doesn't leak this week that won't give you much confidence for next week. Seems like a waste of 300 gallons of water to leak test it at all to me.
 
That is a lot of water. I wouldn't trust it. A new tank might be more up front, but cleaning up and repairing the damage that 300 gallons suddenly released into your house will cost a lot more.
 
So i shouldn't even bother leak testing it. Also, is it worth getting repaired at my lfs or should I just get a new tank?

It's really a rebuild. Take apart, clean and reassemble. Is that what the LFS will do?

If they are just gonna slap another layer on? :eek1:

The details are all important here.
 
Yes they would take it apart and reassemble, only problem is they aren't really a "LFS," because their located 2 hours away from me. Also, for them to reseal it, they gave me an estimate of 10 to 12 weeks. How hard would it be for me to do it? Im pretty sure I would only have to take out one glass panel because the other seams are find.
 
by "reseal" do they mean remove and replace the inner seal, or completely remove, clean and replace the structural seams as well as the inner seal? The latter is what you need to have done. Much more work (and much more expensive).
