for the fecal float do you just use water or sodium nitrate?

i have read to dissolve the fecal matter in sodium nitrate, then put the cover slip on top. as for the smear i was just going to smear it very thinly on the slide and drop some saline solution on it. i have a scope that will got 10x 40x and using oil emerson 100x. i was also thinking of taking it down to the electron microscope and seeing things 1,000,000x
