From the Homeland Security site regarding the storage of emergency drinking water which seems fairly applicable to storing water in our boat tanks.

Do I Need to Treat Water?
Once you properly clean containers, fill them with potable, or safe, drinking water. All public water supplies are already treated and should be free of harmful bacteria. However, as an additional precaution, it is recommended that you add 5-7 drops, about 1/8 teaspoon, of chlorine bleach per gallon of water stored. This precaution protects you against any lingering organisms in storage containers that may have been inadvertently missed during the cleaning process.
