There are many ways to chlorinate an above ground pool. I use a basic blue floating pool chlorinator filled with a few three inch tablets.
It is very important with an above ground pool to never let the chemicals come in direct contact with the liner. If I let my pool chlorinator run out of tablets I always have a supply of granular chlorine on hand. I pour the chlorine directly into the skimmer. That gives the pool a quick boost of chlorine. I then refill the chlorinator and am good for another week or so. During the summer months I find it very helpful to add a bag or two of vinyl shock treatment to the pool every couple of weeks. It is also important to run the filter more hours the hotter it gets.


There are many ways to get the chlorine into the pool, from very simple and inexpensive, to more complex and costly.
Start with a floater and do your homework before investing in an automatic chlorinator. See what your neighbors are using and do some research.

In addition to the automatic systems and the floaters some pool owners prefer just using liquid chlorine. The advantages here are fast acting and very effective. Granules are another option, while I use them for an occasional boost they can also be used for everyday chlorination. However you decide to do it don't forget the extra filter time during the summer months and a regular shock routine.
