a few times with the Air Force but never Giardia or Crypto.
My current preferred method is to filter with my Katadyn Hiker then UV it with my Steri-Pen.
I've used chlor-floc overseas with no problems.
BUT,
my thought was that G&C are probably NOT evenly dispersed so there must be some areas where the concentration is less than in other areas.
THUS, trying to filter an area where the concentration is very thick would be more dangerous than trying to filter water where the concentration is much less.
Last trip the river water was so bad I had planned to wait until I reached the lake and then toss my filter intake over the side and filter clearer surface water.
