Haviland 7523q73 Algaecide 60% Polyquat 1 Qt Pool

Product Description

The HAVILAND 7523q73 is a concentrated pool algaecide formulated with 60 percent polyquaternary ammonium (polyquat) as the active ingredient. Polyquat-based algaecides are non-foaming and non-metallic, making them a preferred choice for ongoing algae control in residential and commercial swimming pools. Packaged in a 1-quart ready-to-use format, this product is applied directly to pool water to prevent and treat green, black, and mustard algae. Pool service professionals and knowledgeable pool owners use this product as part of a routine chemical maintenance program.

This algaecide is suited for use in chlorinated and saltwater swimming pools where foam-free treatment is required. It works alongside standard sanitizers as part of a complete water chemistry program. The 60 percent polyquat concentration makes it appropriate for both preventive weekly dosing and corrective treatment when visible algae growth is present. It is commonly applied during pool openings, closings, and mid-season maintenance visits.
