Re: Bio sand filter - Using a 2 litre PET bottle Thats great if you're really desperate. 90% bacteria removal doesnt quite impress me though ;) Might be a good pre-wash before putting the 'clean' water through your Berkey so that your filters last longer...

Re: Bio sand filter - Using a 2 litre PET bottle a bit off topic but has anyone seen or heard of experiments with water treatment using solid silver as opposed to colloidal silver? as in, what distance would a drop of water need to travel through a pure silver tube to kill most/all pathogens?
