Does the bleach have a negative effect?
If you are on city water, the bleach that you will be adding to the water is far below the amount of chlorine in the city water. Bleach prevents the growth of bacteria. It evaporates quickly which is why it is needed every 48 hours. The biggest health concern with bleach comes when one breathes in the vapors. Therefore, we advise you to avoid the vapors for two hours after you add bleach.
