Pool Closing Without Chemicals for Easier Spring Opening
Pool Tiger enables pool closing without chemicals by using Hydrodynamic Cavitation to keep your water clean and balanced naturally before winterizing. Traditional closings load pools with shock, algaecide, and other chemicals that sit all winter. With Pool Tiger, your pool enters the off-season healthier and opens easier in spring.
Close your pool the natural way. Pool Tiger delivers cleaner winterized water with zero chemicals, zero electricity, and zero maintenance.


Traditional Pool Closing Chemical Problems
Standard pool closing involves heavy chemical treatment to prevent algae and bacteria growth over winter. Shock treatment, algaecide, and winterizing chemicals are added before covering the pool. These chemicals sit in the water for months, creating buildup that affects spring opening.
Pool closing without chemicals is possible with Pool Tiger. By killing pathogens naturally during the final weeks of the season, Pool Tiger sends cleaner water into winter storage. Less chemical buildup means easier spring opening and better water quality from day one.

Set Yourself Up for Easier Spring Opening
How you close your pool affects how it opens. Pools closed with heavy chemicals often have significant buildup when uncovered. Algae may still grow despite chemical treatment. Spring opening becomes a major project requiring additional chemicals and effort.
Pool closing without chemicals means your pool water is cleaner and better balanced when you cover it. Pool Tiger prevents algae growth naturally, so spring opening reveals cleaner water. Your first swim of the new season comes faster with less work.


Protect Your Pool Through Winter
Chemicals that sit in covered pools all winter can damage surfaces. High chlorine levels can bleach liners. Unbalanced pH from chemical additions can etch plaster. Equipment components suffer from prolonged chemical exposure during the off-season.
Pool Tiger balances water naturally before closing, protecting surfaces throughout winter. Without harsh chemicals sitting in your pool for months, surfaces and equipment emerge from winter in better condition.
How Chemical Free Pool Closing Works
Pool Tiger works on the principle of Hydraulic Harmonics. As water flows through the device, it is channeled into proprietary nozzles that convert it to water vapor, super-heating it for a fraction of a second.
Instantly, the water vapor collapses, cools, and reverts back to liquid. This creates a heat signature up to 5000°F that destroys bacteria, algae, viruses, and parasites. Pool Tiger also balances pH naturally, sending your pool into winter with optimal water chemistry.


Easy Installation for Chemical Free Closing
Pool Tiger installs in minutes on standard 2″ plumbing lines. There is no electrical connection needed, no control panel, and nothing to maintain. Use it throughout the season, and your pool will naturally be ready for a chemical free closing.
Close your pool the healthy, natural way. Pool Tiger enables pool closing without chemicals so next spring arrives with cleaner, easier-to-open water.
