This comment led me to a question I have re the amount of bleach needed  
first to purify and then sustain potable water tanks.  What  concentration to 
'shock' it?  And then I assume it would be best to  flush and dilute to a certain 
level?  I can stand a little more than normal  because I have a UV/charcoal 
filter for drinking water.   Thanks.
