Water Testing: After the pump/filter has run for 12 hours, bring a pool water sample from at least 18 inches below the waterline to Pettis Pools in a clean, plastic container for a complete analysis. Any visible algae, leaves, etc should be vacuumed to waste prior to adding the opening kit included in this value pack.

Useful Tips:

When using poolife® Cleaning Tablets, shock treat at least once a week using poolife® TurboShock® shock treatment or poolife® Non-chlorine oxidizer. If you need to increase the level of chlorine in your pool, use poolife® TurboShock® shock treatment. If your chlorine level is in range and you wish to oxidize the organic contaminants without raising your chlorine level, use poolife® Non-chlorine oxidizer.
For best results add tablets to a new, clean skimmer, floater or automatic feeder. Always read feeder instructions before use.
Use your AquaCheck Test Strips to test the chlorine and pH levels at least twice a week.
The continued use of a preventative algaecide such as AlgaeBomb 30 is highly recommended so as not to overtax your chlorine tablets.
