How to use HTH™ 3" Chlorine Tabs Advanced: Wrapped Chlorine Tablets
Place Tab(s) In Feeder, Floater or Skimmer
One tab treats 10,000 gallons of water. Do not add tabs directly to the pool as this could damage surfaces.
Repeat Weekly
For best results, replace your tab every week or as often as needed to maintain a chlorine residual of 1-4 ppm.
