Strong algae protection for busy pool seasons

HTH Algae Guard Ultra is the brand’s strongest algae control, designed to tackle heavy blooms and keep regrowth at bay for up to three months. The formula is non-foaming and fast-acting, so you can treat your water and resume swimming with minimal downtime. This product is non-staining and compatible with all pool types, including vinyl-lined and saltwater systems, offering reassurance for a wide range of setups.

What makes it effective

  • Long-lasting protection: up to 3 months of bloom control for green, black, and mustard algae
  • Kills and prevents regrowth: targets existing blooms and helps stop future outbreaks
  • Non-foaming and fast-acting: simple to add directly to pool water and swim again quickly
  • Non-staining and pool-friendly: safe for vinyl liners and saltwater systems
  • Easy to maintain: pair with HTH Shock products and chlorine tablets for best results

How to use

  • Pour the recommended amount directly into your pool water. No heavy mixing needed.
  • For best results, repeat the treatment every 3 months or as part of a seasonal maintenance plan.
  • Keep a steady routine with other HTH products to support clear, balanced water.

Real-life scenarios

On hot, sunny days when algae can bloom, a quick application can help maintain clarity. Vinyl pool owners may appreciate the non-staining claim, while saltwater pool owners gain reassurance about compatibility. The non-foaming formula also helps keep skimmer baskets clear during treatment.
