The magnification you are using is the strength of the eyepiece multiplied by the lens.
So using a x10 eyepiece with x40 objective gives you x400.
I generally give the whole slide the once over at x40 first, that will allow you to find any flukes pretty easily since they are pretty large. I then go up to x100, x200 and finally x400. You won't see costia very well until you are at x200 or above really.
Hope this helps
