Chlorine Tablet Forms
Chlorine tablets come in three forms from 3- and 1-inch circular tablets, a stick form and finally a granular form. The most popular form of chlorine tablet is the 3-inch tablet that is fed into a floating chlorine feeder. The 3-inch form is slower dissolving, requiring less maintenance and oversight. When the automatic feeder is properly adjusted for your pool, it will feed chlorine into your system for at least one week.
Some things to consider when selecting chlorine tablets are: How many gallons of water your pool holds The type of dispenser you will use How often you wish to refill/change the tablet supply
How Chlorine Tablets Work
As the chlorine tablets dissolve in water, a chemical reaction occurs. The water becomes a light acid; this light acid interacts with algae and bacteria and sanitizes the pool surface and water. The chlorine that is left over freely floats through out the pool maintaining the water's clarity.
Three popular brands of chlorine tablets are: Durachlor Shock Trichlor
