Pool Tiger was designed to harness an all-natural process known as Hydrodynamic Cavitation. In our device this process relies solely on the flow of water as driven by the pool pump.

Constructed of hardy thermoplastic, Pool Tiger has no moving parts. It does not require electricity nor does it contain any cartridges or other components that will ever require replacement.

The effects of cavitation have been known for more than a hundred years, but only recently has this phenomenon been harnessed to provide several important benefits.

Cavitation in our device occurs when water accelerates within the device’s nozzle. This acceleration drops the pressure of the water below the vapor point, resulting in the formation of small vapor bubbles. As the vapor bubbles exit the nozzle, the pressure of the surrounding water causes them to rapidly collapse and revert to a liquid state once again.

It is important to note that the heat produced by cavitation is quickly absorbed by the surrounding water. As such, it does not raise the temperature in the pool by any measurable degree.

Most of the water on our planet is composed of small groups of water molecules randomly joined together by means of shared hydrogen atoms. These molecular groups are irregular in size and shape.

Under certain conditions, however, water molecules can join together in precisely configured groups consisting of sheets of hexagonal cells. Due to their well-defined structure these molecular groups are called “structured water.”

In extremely cold conditions the sheets of hexagonal cells are linked together by connecting protons, which confers solidity. Structured water formed under these conditions is known as ice.

In extremely warm conditions the sheets of hexagonal cells lack the connecting protons and thus they retain the property of liquidity.

In our device the extreme heat and intensive shock waves resulting from cavitation cause the hydrogen and oxygen atoms in affected water molecules to temporarily disassociate and then re-associate as the water cools. As they re-associate, they do so in sheets of hexagonal-shaped cells.

Whether solid or liquid, structured water is said to be exclusionary because it tends to reject any material that is not structured water. This is why icebergs, which are formed from salt water in the oceans, contain no salt.

In liquid form, structured water tends to collect at hydrophilic surfaces, such as pool walls, floors, pipes, equipment and even the surface of the water itself. There it will reject any material that is not structured water.

To learn more about structured water, we recommend Dr. Gerald Pollack’s excellent book entitled, The Fourth Phase of Water.

Pool Tiger operates on the flow of water as driven by the pool pump. It activates at a minimum flow rate of 8 GPM. In essence, the device converts the energy provided by the pump into a variety of benefits.

The more the pump runs, the more Pool Tiger is doing to sanitize, clarify and enhance water quality as well as protecting pool surfaces from buildup and staining. Should heavy bather loads, inclement weather, algae infestation or other conditions detrimentally impact water quality, we recommend that pump run times and flow rates be temporarily increased until water quality improves.
