Somebody's way off!

The "standard" measurement is: 1 cup per 15 gals of water.

Now keep in mind that there are different levels of chlorine mixes. The typical house hold bleach (Purex, Clorox) is only at 3%...whereas pool chlorine is a lot more. The above measurement is for house hold bleach.

FWIW, your owner's manual will probably have a "winterization" section that will stipulate how much to use. Check it out first.

I've read a few other opinions. Some say one teaspoon for 5 galleons. Some say one teaspoon for 10 gallons. Some say it depends on how quickly you want it to be disinfected.

It also depends on how "dirty" the water is. Start with a lesser amount. Maybe 1 teaspoon per 16 gallons as above. Stir and wait a bit, if the water has a slight chlorine smell then you added enough. If you can't smell it at all, add more until you detect a faint odor of chlorine.

If you really want to be sure too can buy test strips to measure the chlorine parts per million.

6 drops per gallon. 6 drops equals 1/16 teaspoon. 6 teaspoons equals 1 ounce. Therefore: 1 teaspoon for 16 gallons or 1 ounce of bleach for about 96 gallons of water. That is the Chlorox manufacturer recommendation. You can google their web site for the ratio.

I use about 1/2 oz for my 60 gallon tank.
