The HTH Clear Blu Cube is a convenient slow-dissolving clarifier that gradually releases a flocculant to trap fine debris that the sand filter cannot catch, restoring water clarity and adding sparkle. It is ideal for weekly maintenance, after storms, or following shock or algaecide treatments.
Swimming is safe 20–30 minutes after application with the pump running, and its slow-release formula typically lasts over a week depending on pool conditions. Registered under Act 36 of 1947, it is a trusted solution for maintaining sparkling residential pool water.
To use, backwash and rinse the filter, and clear the pump and skimmer baskets. Remove the cube from its plastic packaging and place it directly into the skimmer basket, ideally under the pressure plate. Run the filter on a normal cycle; the cube dissolves gradually, capturing debris. If the automatic cleaner slows down, backwash the filter immediately.
