One thing not mentioned in this thread what your tanks are made of.
Shocking is ok with stainless, glass and plastic tanks. It should not be done on aluminum. Clorox (sodium hypochlorite) or any chlorine based agent is very agressive chemically.
In contact with un-coated aluminum it will start the formation of aluminum chloride scale (which will clog you filters), it will pit the surface of the aluminum, and if there are any minor welding flaws in the tank, it will take them from minor to major. While iodine based agents will do the job, they will leave a lingering "off" taste and quite a few folks are seriously allergic to iodine.
If you have aluminum tanks, you are better off using periodic steam cleaning through the inspection port and aggressive filtration.
Also, while shocking is effective on tanks other than aluminum, it is not enduring. Each tank fill will bring in small amounts of stuff you would rather not have in the tank.
A good filtration system pays for itself in good health, and if you can't filter, then a 15 minute rolling boil of any water you plan to consume is next best.
