The surface area of the capsule exposed to water remains constant so, unlike standard 200g tablets, your pool water has an even amount of chlorine going into the pool from start to finish with no chlorine lock

        • HTH SUPERCAPSULES SHOULD BE PLACED IN THE SKIMMER BASKET ONLY. NEVER USE THE CAPSULES IN FEEDERS OR AUTOMATIC CHLORINATORS.
        • Do not remove the sleeve. Once all the chemical has dissolved, the plastic sleeve will float and the sleeve can then be removed from the skimmer and discarded.
