I have a brand new aqueon evolve 8. It's been going through a dry start with HC and everything was good. Filled it today and I noticed a puddle under the tank. Looked at the back and there was a dripping, but steady coming from about 2 inches across the back bottom seam. It seems siliconed tight but somehow water is getting through. I couldn't reach aqueon now so I drained it as much as I could. Propped up the back end and in emergency used some JB WaterWeld (epoxy potable water safe, reefers use it) over the leak and it stopped leaking. It has a set time of 15 minutes and a cure time of 1 hour. Do you think this would be safe to use or could something bad happen? I don't think 8 gallons of water is a lot of pressure but I don't want it to bust or something. It was leaking from the black wall part, like the filtration chamber part. I will post pics in a second...

Here are the pics of what the seam is like and the epoxy I put on it...

If the tank is new, get it replaced.

If it's not under warranty, you'll likely want to use silicone or another aquarium sealant and go through some of the DIY threads.

It's two month's old so I have to contact aqueon but still pretty new. Tried calling but got voicemail multiple times even though they say they are open. I emailed them but they probably wont do much since I modified the filter a bit even though it has nothing to do with the leak. I'm just so aggravated because I had this great dry start for 8 weeks and now it was just possibly wasted time.

Epoxy cured and I filled it back up. 5 hours and so far no dripping or leaks. I also contacted aqueon via email.
