HTH Stick

HTH Stick is a 300g Chlorine Capsule and  comes in a 4.5kg container. This product was previously known as Fi-Clor Supercapsules but have been rebranded as HTH Stick Tablets for 2022.

The HTH Stick Capsules are especially recommended for indoor pools that are open all year round, as the chlorine is stabiliser free. This helps to prevent a problem known as chlorine lock when the Cyanuric Acid in stabilised chlorine product becomes too high.
