Quick Question - Mild Steel or Ceramic

[BSVKilbey]

Hi all,

Just a quick one.

I am looking at modifying an old tank and the first thing that popped into my head is the Impeller.

I have removed it from the filter but how can I tell if it is Ceramic or Mild Steel? I would need a Ceramic one to prevent rusting from salt water.

Even the manufacturer's website doesn't say.

It is magnetically held in which I assume means steel, however, if I change it for Ceramic is it then not going to hold in place?

Thanks in advance

The shaft is not what turns the impeller. The magnet mounted on the shaft will. You need to disassemble the cover and simply pull out the impeller. If it's steel is Shiney like chrome or if it's whitish /yellow is ceramic.

Ah understood!

The good news is, that it is plastic. So good to go for Marine :)

Thanks for helping
