Also..you can easily get rid of the chlorine in your water with a little potassium metabisulfite (campden tablets). One 1/2 gram tablet will treat 20 gallons of water, just break a tablet into an appropriate sized section and throw it in, the reaction is very quick and the heating process should drive off the sulfites to prevent any possible reaction with the yeast. This is especially important if you have chloramine in your water.
You can feel good, good, good about hood.
