Hot Tub Water Care


Your hot tub water needs to be treated with certain chemicals to maintain its cleanliness.

 

Please see our accessories page for chemical prices.

Blue Whale Spa - Hot Tub Chemical pack

Sanitiser levels, Ph Levels and Total Alkalinity can be measured with readily available water testing strips. As you use your tub, chemical levels will change as they do their job, keeping the water clean. Remember to only add small quantities of chemicals to your water as once it is dissolved into the water it is impossible to take any out.

Sanitiser

A sanitiser, Chlorine or Bromine can be used in either granule or tablet form. Granules dissolve into the tub water quickly and can be used to boost  chlorine levels quickly. Tablets are slower to dissolve and are floated around in the hot tub in a floating dispenser. This can keep Chlorine levels more stable, reducing the need for regularly dissolving granules into the water. Never mix Chlorine and Bromine in the same water!

Blue Whale Spa | Hot Tub pH and Total Alkalinity Reducer

Ph

Also required is a chemical for controlling the Ph of the water. Either a Ph increaser or a Ph Reducer to keep the Ph within a safe level.

Blue Whale Spa | pH Plus for Hot Tub

Total Alkalinity

This is the measure of the ability of water to resist changes in pH. Total Alkalinity increaser is added once the Chlorine content and the Ph level are correct.

Testing Strips

Testing strips have coloured pads which change colour dependent on the amount of the above chemicals dissolved into your water.

Dip the testing strip in your water and compare the colour of the pads on the strip to the coloured squares on the testing strip container.

If the coloured pad is the same as the square patch on the container you do not need to add any chemicals.

If the coloured pads are different to the squares on the container add small amounts of chemicals to the water re-testing each time until the coloured pads match the squares on the container.

Blue Whale Spa | Non Chlorine Shock

Oxidiser (Shock)

This should be used as directed on the package once a week or after the spa has been used for several hours by a larger than normal number of people.

These chemicals could be the only things you need to put into your water to keep it clean. There are however various other things that affect the quality of your water as the tub is used. All of these chemicals should be used sparingly in small amounts retesting after each addition of chemicals.

Blue Whale Spa | Hot Tub Instant Filter Spray

Filter Cleaning

Dependent on the amount of use that your tub gets you should clean your filters every two weeks. There are various overnight soak solutions or instant cleaner sprays that can keep your filters clean.

The most effective method of extending filter life is to have a pair or two sets of filters to rotate. Whilst one set is in the tub working, the other set is cleaned and dried out and then when it is time to clean the filter again you simply replace with the clean dry filter.

Blue Whale Spa | Water Changing

Water changing

Check the water level in your tub regularly and top up as necessary.

If you keep a check on your water and chemical levels either every day or each time you use the tub and add the necessary chemicals you should be able to keep your water in the tub for up to three months.

After three months it is recommended that you drain the tub, clean the shell and jets and then refill with clean water.
