tiny leak?

[derf9h]

I bought a used 75 gallon tank about 8 weeks ago. It was in fantastic shape. When I filled it up and let it sit for almost 2 weeks in my garage it showed no signs of leaking. I now have had it set up in the house for almost 6 weeks. The other day when I was tinkering with the sump I noticed there was water around part of the plastic support on the bottom of the tank. There was enough to cause it to form a drip, but not to actually drip, and you could definitely see there was water up in between the glass bottom and the support. If you look in the pictures you can see exactly where the water is. I wiped it down last night before I went to bed and when I woke up you could just barely see any kind of wetness, so I left it alone. When I got home, the edge is wet again to the point of almost dripping. This definitely worries me...

I'm open to options. I would hate to have to tear down my new tank.

Can I just put some silicone around the support and the glass?

How much are new 75 gallon tanks? Where can I get a good deal on a 75 gallon tank?


AAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHH. I have to yell because my wallet is yelling at me....






Thanks for the help.

I hate to say so, but this is a problem. Water works somewhat by 'attraction,' ie, when the first few molecules find their way in, they draw others after them, and pretty soon the leak gets worse.

Your tank has been in place and under pressure long enough to have squeezed out any water that got under the rim during setup, so the unfortunate conclusion is that this tank has a pinhole leak, probably in A corner seam, but not necessarily THAT corner seam, that is getting worse.

Check your water level to be sure wave action isn't pushing water over the top rim; but if it's not coming from there, I think you know your next step...get a Brute trashcan, siphon into that for all fish that won't fit into your qt tank, get a second one for your live rock, and get ample filtration on it: this disruption may mean qt'ing your corals/fish through a minicycle of about a week if you can save your sand and keep your rock alive.

You can fix this with some proper tank sealant: I'd do every single seam just as a failsafe. Dry it completely, completely re-seal, allow to cure, then re-water and test. Talk to the DIY forum about it: they'll know modern materials and procedures---I haven't had to do this since the days of black tar sealant.

Greatest sympathy: I moved my system this spring and it's a PITA, but better done now while you have time rather than on some late night when you don't. Maybe somebody else will have a better outlook for you, but I really, really fear this one needs to be taken care of.

It could be a leak and it could possibly get worse.
It could be a leak and it could possibly seal itself.
It could be condensation and nothing to worry about at all.
A few photo's would be beneficial.
