HTH™ Green to Blue Shock Treatment is a powerful pool shock system designed to turn a green, algae-filled pool back to a sparkling blue fast.
- Ideal for pool opening or anytime water looks like pea soup, this two-step green to blue swimming pool solution works in as little as 24 hours.
- Step one kills invading bacteria and algae, while step two settles fine particles to the bottom for easy vacuuming to waste.
Built for results, HTH™ Green to Blue helps you recover from severe water problems with confidence and control so you can get back to swimming sooner.

Note before purchasing:
This product may not be right for every pool - it is not designed to work with pools that cannot vacuum to waste. Make sure that you have the ability to vacuum the debris out of your pool without it passing through the filter. Read all label directions carefully before using this product.
