eheim impeller ques
 

I was on the eheim website & looking at the 2228 filter parts list, shows 2 different impellers avail. They look the same but the difference being that one is 50hz & the other 60hz. Does this mean; stronger magnet=more output

I looked for the impeller your talking about on the Eheim site and I could only find the 60hz model.
We use 60hz in Canada.
Other countries like Australia use 240v at 50hz.
