Anything I've read indicates that it would be the same as any level set
for
Giardia lamblia. This doesn't seem right however as the oocysts of
Cryptospordium are so much smaller and able to pass throught filters
designed to
filter out Giardia. Any article by Fayer and Unger, or Dr. Harley Moon
would probably give you more info.
