The Foundation of Clean, Safe Pool & Spa Water

Every sparkling pool begins with effective sanitization. Without a proper sanitizer, water quickly becomes a breeding ground for bacteria, algae, and harmful contaminants. That’s why chlorine, bromine, and mineral sanitizers are the backbone of pool and spa care. These systems continuously destroy germs and organic waste, keeping your water clear, safe, and healthy.

At Benchmark Pool Supply, we offer a complete selection of pool and spa sanitizers to match every system and preference. Whether you rely on traditional chlorine tablets, prefer the gentler feel of bromine, or want the convenience of mineral-based systems, we make it easy to choose the right option for your water care routine.

For best results, pair sanitizers with Shock Treatments for powerful oxidation, Pool Balancers to stabilize water chemistry, and Specialty Chemicals for targeted treatment.

  • Prevents Algae – Stops growth before it takes hold.
