I'm not familiar with CHLOR-FLOC, but by the name I'd guess it uses chlorine as the purifying agent. I have used chlorine and it is supposed to be very effective. Are you planning on using the tablets and the filter to treat the very same water (double treatment)? If so, that sounds like overkill to me. Using a good filter alone should be sufficient and will avoid adding an unpleasant taste from chemical treatment. <br><br>
