Yes, rust is bad in the tank, a pal of mine lost all his sps due to a rusty magfloat, see if you can get some ceramic impellor shafts from the sponsors, perhaps George at Tunze could help.

Yip rust is a concern to use all, but having said that overseas there are owners of magnificent tanks who purposely have a rusting razor blade in their tank as this is a form of Phosphate remover???? Doesn't make sence does it???
I often get a bit of rust on my one or 2 SS pump impellors but I clean when the pump is blocked and under performing.
