1 / 7ADOSSY 3-inch Stabilised Chlorine Tablets, 5.5 lb
ADOSSY 3-inch Stabilised Chlorine Tablets are slow-dissolving tablets advertised for pool, hot tub and spa water treatment. The listing describes a four-function formula and claims extended release, but gives conflicting dissolve-time guidance, so the stated dosing interval should not be treated as settled.
At a glance
- A single tablet is presented as a sanitiser, stabiliser, algaecide and clarifier.
- The listing recommends use in a floating dispenser, skimmer or automatic chlorinator.
- The product is claimed to be UV-stabilised with cyanuric acid.
