Plastic tank trim "wicking" water?

If the plastic is causing this issue run the take lower for a few days and put a bead of silicone to seal that gap. Done deal.

I think theres a issue with some plastic trim were they silicon it to hold it on but not to seal it best bet is to lower the water level and run a bead around the inside of the tank. Make sure it's reef safe. And try to let cure as much as possible before raising the water back up.

Thanks for the input guys. The prospect of an actual leak had me a little paranoid.

I guess I'll figure out some way to sillicone it.

Unfortunately my overflow box doesn't lower on the inside much past the trim. Maybe I'ts time to swap it out for a new one so I can adjust the water level where I want it.
