Buying Guide

  • Pool size compatibility: Choose a kit aligned to your gallons (e.g., up to 7,500, 15,000, or 35,000). Larger kits reduce the need for extra purchases but may oversupply smaller pools.
  • Starter vs. maintenance focus: If you want quick opening with fewer steps, pick 5-in-1 or deluxe kits. If you’re balancing all season, a basic kit plus periodic refreshers may work best.
  • Algae prevention: Algaecide inclusion helps keep water clear longer, especially in warm climates or high sun exposure.
  • Sanitizer compatibility: Check whether the kit uses sodium dichlor, or is designed for use with chlorine, saltwater, or other sanitizers.
  • Clarifier and filter impact: Clarifiers improve filtration efficiency but require proper backwashing schedules to avoid buildup.
  • Ease of use: Pre-measured sachets simplify dosing; kits with step-by-step instructions reduce guesswork for beginners.
