URGENT HELP NEEDED!!

[daplatapus]

I get something very similar. But I have an old tank with a cracked plastic rim. When my koralia pumps kick in or my water level gets a bit high capillary action sucks the water up and over the glass (but under the plastic trim) and it dribbles down the front and side panes of my tank. I guess there's either no silicone left in spots of the plastic and the glass and water can flow between them.
How old is your tank? Does it ave a trim on it? Is the plastic trim cracked or chipped anywhere?
