Good afternoon. I have three MP40QD running. On the back wall of my 405. Yesterday when cleaning the wet sides I noticed the on one of them.

Not sure how it happened. Nevertheless, it is back in the tank and in operation. Will the exposed metal cause an issue? Please help.

Thanks.

Could rust. I think Insaw a post one time where the inside of the mp was leaking copper into the tank.
