BioGuard Spot Kill (product number 23107BIO) is a highly concentrated, fast-acting granular algaecide specifically formulated to kill stubborn, localized algae growth, particularly black and green spots, in swimming pools.
Key Features and Description:
-
Purpose: Spot Kill is designed as a problem solver to target and eliminate existing algae spots on pool surfaces. It is especially effective against tough black algae.
-
Active Ingredient: The main active ingredient is Sodium dichloro-s-triazinetrione dihydrate (99%), a concentrated form of chlorine.
-
Form: It is a highly soluble, granular product that is applied directly to the affected area, either by broadcasting it over the spots or applying it directly into the water near the growth.
-
Surface Compatibility: This specific formulation (23107BIO) is ideal for use in pools with vinyl, fiberglass, painted, or colored plaster surfaces. A different product, Spot Kill WP (for white plaster only), is available for bleachable surfaces.
-
Water Balance: It has a near-neutral pH (around 6.0 when in a 1% solution), which means it will not significantly upset the pool's overall water balance.
