How to use

HTH® 3" Chlorine Tabs Ultra

1. 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.

2. Repeat Weekly

For best results, refresh your tab every week or as often as needed to maintain a chlorine residual of 1-4 ppm.
