hmm, guess i rocked the boat a bit there, did come over a bit strong, its just i feel as a cash strapped student (and being after cheaper options), buying bottles and stuff just cos its in a starter pack can be a bit of a waste of money and/or beer (if a pressure keg get contaminated etc its a bit off putting for a beginner) AND yes never used a pressure keg so wouldnt really know, just sounds like a bad idea for me. Though i stand by the campden tablets not being ideal, if they were its what hospitals would use, as it stands bleach is faster(campden takes a while for fumes to build), better (can actually dissolve/remove mild debris) and doesnt require a internet or lhbs to provide it (though is bad if its left in the brew, so can do some harm which campden can't-why given to beginners).
