Six product categories that cover the full pool maintenance cycle — from daily sanitizing to seasonal deep cleaning.
Advanced Chlorine Sanitizing
HTH chlorinating products deliver consistent, reliable sanitizing power to keep pool water crystal clear. Available in tablets, granules, and sticks for flexible dosing that fits your pool routine.
Super Shock Treatment
Fast-dissolving shock treatment eliminates contaminants, restores clarity, and breaks down chloramines in hours — not days. Swim-ready in as little as 15 minutes with select formulas.
6-Way Water Balancing System
Complete water chemistry management with pH increasers, pH decreasers, alkalinity adjusters, calcium hardness, stabilizer, and phosphate remover. Balanced water protects equipment and extends pool life.
Test-To-Swim App Technology
The free HTH Test-To-Swim mobile app reads your test strip with your phone camera and provides personalized, step-by-step treatment recommendations. Smart water care made simple.
Algae Guard Protection
Powerful algaecide formulas prevent and treat green, yellow, and black algae. Year-round protection is critical in Florida where warm temperatures fuel algae growth 12 months a year.
Filter & Water Clarity System
Clarifiers bind microscopic particles for easy filtration, while filter cleaners remove built-up oils and scale. Together they restore flow rate and keep water sparkling.

Understanding Pool Chemicals
Sanitizers
Chlorine Tablets: Slow-dissolving 3-inch tablets for consistent daily sanitizing. Place in a floating dispenser or automatic chlorinator. The backbone of pool maintenance.
Chlorine Granules: Fast-dissolving granular chlorine for quick adjustments. Ideal for raising chlorine levels between regular treatments.
Bromine: Alternative sanitizer preferred for spas and hot tubs. Effective at higher temperatures and gentler on skin than chlorine.
Specialty Chemicals
Clarifiers: Bind tiny particles too small for the filter into larger clumps that can be captured, restoring water clarity overnight.
Algaecides: Preventive and curative treatments for green, yellow, and black algae. Essential in Florida where warm water breeds algae year-round.
Phosphate Removers: Eliminate phosphates that feed algae growth. Especially important after heavy rain or lawn fertilizer runoff.
