Turn green pool water into blue, fast

The HTH 2-Step Green to Blue Swimming Pool System tackles stubborn algae blooms and refreshes water in as little as 24 hours. This two-pack solution pairs a strong algae-fighting shock with a powerful flocculant for easy cleanup, delivering a visibly brighter pool without a complicated routine.

Pack I uses a Cal Hypo-based formula to jump-start clarity, while Pack II pulls fine particles to the floor for quick removal during vacuuming. Importantly, no cyanuric acid (CYA) is added, helping avoid overstabilization and keeping chlorine levels responsive to sun exposure.

The result is clearer, blue-tinted water that looks inviting, along with a practical approach that suits many pool styles. It works best for pools that can vacuum to waste and is gentle enough for vinyl-lined surfaces, reducing the worry of liner fading.

How the 2-step system works

  • Algae control and color return: Pack I shock kickstarts the process to clear green water.
  • Debris removal: Pack II flocculant gathers fine particles so vacuuming is faster and cleaner.
  • Balanced chemistry: The formula avoids CYA buildup, supporting effective disinfection during sunny days.
  • Versatility: Suitable for most pool types that can vacuum to waste, including vinyl liners.
  • Ongoing balance: Pair with HTH 6-Way Test Strips and test water twice weekly to maintain clarity.

Practical usage tips

  • Before adding Pack I, test the water and remove visible debris for best results.
  • After the transformation begins, run the filter and vacuum to waste as the water clears.
  • Recheck chemistry after treatment and rebalance as needed with your test strips.

Best used at seasonal openings or after severe algae events, this system provides a straightforward path to crystal-clear water without extra steps. By avoiding added CYA, you maintain a balanced chlorine response that supports summer fun with a sparkling pool you can see and enjoy.
