Looking for ideas on sump leak.

[mrcoffee2]

My nuvo 30 gallon has a leak between the tank and the sump. I am assuming it is the seal that runs along the bottom of the tank. The problem is my tank is not getting much overflow from the top so things like my chaeto and skimmer are suffering a bit.

Leak is some where along that red line.

Does anyone have any ideas to fix this that does not involve tearing it down? I was thinking possibly adding a sandbed, or a stronger return pump to make up for the water being pulled underneath.

Maybe there is some kind of rubber seal I can buy and put down?

I talked with IM. Their first suggestion is to pull it all out and reseal it. They said it is actually fairly easy.

They also mentoned I could try coral epoxy and throw a sand bed on top of it, but it doesnt really fix the problem.

Lastly they said there is a seal at homedepot I could try.

Looks like I might be resealing it... I have never done anything like that before does anyone have any pointers?
