The BIOLAB 90243skr is a three-part pool opening and winterizing chemical kit designed for use in residential and commercial swimming pools. The kit includes 90-Day Algae Prevention and Remover to kill and inhibit algae growth, Metal Klear to prevent metal staining and scale, and Free and Klear to clarify water and eliminate phosphates. Each component is packaged in a one-quart bottle for a total volume of three quarts. Pool service professionals and knowledgeable pool owners use this kit at spring opening or fall winterization to establish a clean chemical baseline before seasonal treatments begin.
This kit is suited for seasonal pool maintenance applications where algae control, metal staining prevention, and phosphate elimination are needed in a single treatment package. It is appropriate for above-ground and in-ground pools during opening or closing procedures. The three-component format allows technicians to address multiple water chemistry concerns simultaneously rather than sourcing individual products. It is commonly applied as part of a structured opening protocol before chlorine and pH balancing products are introduced.
Designed for use in residential and commercial swimming pools as part of an opening or winterizing chemical treatment program. Consult individual product labels for compatibility with specific pool surface types and sanitizer systems.
Pool chemical applications should be performed by a qualified pool service technician or a person familiar with water chemistry and chemical handling procedures. Ensure the pool pump and filtration system are running before adding chemicals, and follow label directions for dosing sequence and recirculation time. Wear appropriate personal protective equipment including gloves and eye protection when handling pool chemicals. Store unused product in original containers away from heat, open flame, and incompatible chemicals.
