Slow-Dissolving, Health Canada Approved Sanitizer

Lawrasons Chlorine Pucks & Tablets are premium 90% stabilized chlorine designed for effective, long-lasting sanitation in outdoor swimming pools. These slow-dissolving pucks release chlorine gradually, maintaining consistent sanitizer levels while reducing the need for frequent dosing. Stabilized with cyanuric acid, they help protect chlorine from sunlight breakdown, making them ideal for Canadian summer conditions.

Health Canada approved for residential pool use, Lawrasons Chlorine Pucks are compatible with most chlorine-based pool systems and can be used in floaters, skimmers, or automatic chlorinators. Regular use helps prevent algae growth, destroy bacteria, and keep pool water clear, safe, and inviting throughout the season.

Available in 750 g, 2 kg, 7 kg, and 20 kg sizes, these chlorine pucks suit everything from small above-ground pools to large in-ground pools and full-season maintenance needs. Whether you’re topping up weekly chlorine levels or planning for long-term pool care, Lawrasons Chlorine Pucks deliver dependable performance and professional-quality water sanitation.

Pro-Tip: Keep Chlorine Out of Your Skimmer
Want to make your skimmer basket and pool liner last longer? Stop putting chlorine pucks in the skimmer. The high acidity of concentrated chlorine makes plastic baskets brittle and can cause "bleach spots" or wrinkles on the liner near the skimmer opening. For a safer and more effective way to sanitize, use a specialized feeder. We offer high-capacity Floating Dispensers that move around the pool for even distribution, or permanent In-Line and Off-Line Chemical Feeders that plumb directly into your system to keep the chemicals away from your delicate plastic parts.
