Salt Water Chlorinators -Spas
Salt Water Chlorinators are great for spas. There are not many that are actually designed for spas, but they are starting to get popular. While you can use an model for a spa, you must look at controlling the amount of chlorine produced, so you do not over chlorinate. This is why it is best to use a unit specifically designed for a spa. The best units have ORP control which keeps the chlorine level exact automatically.
