Hi all I'm just renewing all my tank rubbers and I've noticed a very small patch of very light rust (100mm2 most of the paint is still there it's like pin prick rust) around the strainer the rest of the tank is like new so would you leave it until it gets worse ( there is no sign of any **** in my filter) or would you use a tank liner if so which one and is it easy to do.
Thanks phil
