Sanitizing fresh water tank? Bleach?

The standing method is 1/4 bleach (Do not use low splash) to every 15 gallons of water.
On their website, Clorox says that 30 minutes is sufficient but I usually leave it overnight.
To completely kill the bleach in the water and remove any smell or taste of it, poor in a few ounces of hydrogen peroxide (perfectly safe and amount doesn't really matter), run it through the lines and then drain and refill.

I use Hydrogen Peroxide myself instead of bleach. Has no smell, kills everything and is safe to ingest diluted. Never been fond of the bleach smell. I use 35%.
