When mine had mites, I just took her out and had three or four successive water baths set up. She spent about five minutes in each one, and I poured water over her back gently, then switched her to the next one. By the time I got her to the last bath, there were no mites left. Then I just deep-cleaned her tank before putting her back in. It was a pretty minor mite problem, but it seemed to work pretty quickly.
