Instructions To Correct Low Total Bromine Levels in Swimming Pools using Relax Bromine Granules

Calculate your pool water volume, if in doubt call us and we can advise you.

Test your pool water for Total Bromine, if lower than 2ppm you will need to increase it. The desired levels should be between 2-5ppm

Add Relax Bromine Granules at a rate of 3g per 1,000 litres to increase the Bromine level by 1ppm. Ideally, aim to keep the Spa Bromine levels around 4ppm or 5ppm.

Check the Total Bromine levels regularly and aim for a reading of 4-5ppm to ensure the water is clean and safe.

HOW DOES THE POOL TIGER WORK

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. 

HYDRODYNAMIC CAVITATION

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.

This rapid change in water’s states of matter creates:
- High levels of infrared energy (heat )
- Intensive shock waves

These factors are sufficient to:
- Oxidize and destroy exposed contaminants – this improves sanitation and reduces the need for chemical treatment
- Initiate the gradual decomposition of acids – this raises pH and eliminates excessive levels of cyanuric
- Change the polarity of suspended particles, causing them to agglomerate to a size at which they are easily captured by the filter – this clarifies water and creates a more inviting swimming environment
- Affect the bonds between the hydrogen and oxygen atoms which constitute water molecules - this produces a phenomenon known as "structured water"

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.

STRUCTURED WATER

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.

Pool Tiger is very easy to install. It ships fully assembled with unions and requires no electricity. Unless a loop is required due to space considerations on existing equipment sets, an experienced installer should be able to complete the installation within 15 minutes.

On new pools, the Pool Tiger should be installed last on the return line. On existing pools with a heater, it should be installed before the heater on the return line. If the return line is too short to install the Pool Tiger in line, use 8 elbow fittings and extra pipework to create a loop. Pool Tiger can be installed horizontally, vertically or diagonally. 

IMPORTANT: Pool Tiger will not work if not installed in the incorrect direction.

INSTALLATION VIDEO BY R C MAINTENANCE, BASED IN BEXLEY

Pool Tiger does not need a separate electrical supply, but operates on the flow of water as driven by the pool pump. It activates at a minimum flow rate of 1.8m3 per hour. 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.

    PRODUCT INFO:

    HTH Clarishock is the new name for Fi-Clor Rapid Clarifier and is an ultra concentrated liquid specifically designed to give the best pool water clarity on swimming pool, with sand or glass filters, when compared with other Brands of swimming pool clarifiers.

    Following the directions, and dosing with the simple to use measuring cap, will return your pool water to crystal clear and keep it like that if used regularly.

    HTH Clarishock works both as a clarifier and flocculant. Fine particles suspended in your swimming pool water that cannot be retained by the filter, make the water cloudy. HTH Clarishock helps particle aggregation, the process by which suspended colloids clump together and are either collected in the sand filter, to be backwashed out later, or come out of suspension as a floc which then collect at the bottom of the pool as debris to be vacuumed to waste.

    Instructions To Clear Cloudy Water in Swimming Pools using HTH Clarishock Rapid Clarifier

    Calculate your swimming pool water volume, if in doubt call us and we can advise you. Check pool water balance and ensure Chlorine level is between 1-3ppm & pH level 7.2 - 7.6

    Restoring Cloudy Water To Crystal Clear: Dose rate of HTH Clarishock Clarifier: 100ml Per 50m3 (50,000 litres / 11,000 UK Gallons). In order for HTH Clarishock to work your filtration must be running. If debris collects on pool floor, vacuum to waste. Regularly check filter pressure and backwash if required. If pool is still cloudy after 24 hours backwash and repeat dose.

    Preventing Cloudy Pool Water: Dose rate of HTH Clarishock Clarifier: 100ml Per 50m3 (50,000 litres / 11,000 UK Gallons) once a week.
