If you're taking on municipal water, it's chlorinated, and will typically have about 2ppm of chlorine residual. That takes care of any pathogens that it may encounter. If your tank is clean, there's no need to add anything.
In order to start with a clean system, you may want to shock the whole system with a 50ppm concentration, about 12 oz./100 gal. or 10ppm- about 4 oz/100 gal. Contact time is 6 hrs @ 50 ppm or 24@ 10 ppm. After the desired contact time, just flush out until smell is gone. Overkill isn't necessary, it just makes flushing more trouble. More does not do it better.
Once the system is clean, as long as you're using municipal water, nothing further is needed. If you're using on-site water (private well), you can treat to 1-2 ppm, or about 1/2-3/4 oz per 100 gal. Folks who insist on regularly dumping cupfulls of clorox into their tanks are unnecessarily exposing themselves to unacceptable chlorine levels, and it's not good for the tanks, either.
There's an inordinate amount of worry regarding tanked water on board. Start with a clean system, turn the water regularly, your water will be just fine.
