I was cleaning my tank today and noticed that there is some water getting behind the seal in the corner of the tank. I'm not to sure how long its been happening but it looks pretty bad no pics atm but I will post one when light s are on in the am. Any way my question is, is there some kind of sealent that I could use under water? Its like half way down and id hate to have to drain my tank. Any suggestions would be really appreciated. I don't know what I would do if my seal broke and my tank drained everywhere id be devistated.
