T&T: Bleach in potable tanks

[Keith]

I just shocked my tanks last week. I use 1 gallon per 100 gallons to shock. 
Put in the bleach, fill the tanks, then let it run through everything and 
let it set 5-12 hours or so, then pump out and flush. With my big tanks, I 
use a 110V portable pump to pump out the bleach, then scrub and blast with a 
hose as best I can. Then just refill with fresh water.

If you use regular chlorinated city water, you really don't need to add 
bleach, but if your water is suspect, or you just want to make sure, one 
tsp./5 gallons is what health departments recommend.

If you need to do some conversions, this web site is great, for just about 
any kind. http://www.convert-me.com/en/
For instance, if you wanted 20 tsp. for a 100 gallon tank, that converts to 
about 7 tablespoons or 0.4 cups.
