I haven't included any water purification options in my psk yet. Has anyone tried the Coghlan's water treatment tablet's? Are they any good? <br><br>Also, I've collected a couple of the mini tobasco bottles from American MRE's and have been trying to decide what to do with them. I was thinking of filling one with javex and using that as a water purification system. Is Javex suitable for this? I've heard that it is. The bottles are so small that they only release a drop at a time and they would fut nicely in an Altoids tin.<br>
