Hi, I just got a Katadyn Hiker Pro filter for christmas, for my thru hike this spring. The day after christmas, i put it all together to give it a test run. when i was done, i just put it in its bag, all together. i didnt touch it until about a week ago, when i removed the element and was surprised (although looking back i really shouldn't have been) to find that both the plastic sheet wrapped around it and the element itself had some black spots of mold. i have been reading online and the general consensus seems to be that you should pump through some water mixed with a little bleach to clean out the filter when you're done using it. my question is, will this cure my existing mold problem, or is it meant only to prevent mold from growing in the first place? if it's already moldy, do i just need to buy a new element? i would appreciate any advice. thanks.
