Solenis Blackout Trichlor Granules

A 90% trichlor concentration provides a high-strength, concentrated dose of chlorine that is exceptionally effective at rapidly killing bacteria and algae. Because it is stabilized, the chlorine resists degradation from UV sunlight, allowing it to remain active in your pool water for longer periods.

While this product is highly effective for most standard pools, the high concentration of trichlor can be harsh on certain surfaces like vinyl liners if not applied correctly. Always ensure the granules are fully dissolved or broadcasted evenly to prevent bleaching or staining on pool surfaces.

The granular form is specifically engineered to dissolve rapidly upon contact with water. This quick-dissolve feature helps prevent the granules from settling on the pool floor, which minimizes the risk of staining and ensures the chemical is immediately available to sanitize the water.

This product is versatile enough for both. While it is powerful enough to clear up cloudy or algae-ridden water as an intensive shock treatment, it can also be used as part of a regular maintenance routine to keep chlorine levels consistent and water clear.

Yes, because this formula is already stabilized, it includes the necessary protection against UV degradation. You should still test your water regularly to monitor your cyanuric acid levels, but you will not need to add extra stabilizer specifically to protect this chlorine from the sun.
