The Hot Tub Chemicals Guide

Are you unsure of what chemicals you need to maintain and clean your hot tub, spa or pool? Or maybe you’re a new hot tub owner and you are unsure of the right chemical dosage amounts that you require. Whatever your needs, here at SpaChem we have got you covered with our how-to guide.  As hot tub chemical experts, at SpaChem we only supply products that have been extensively tested and have been designed for quality use on hot tubs, spas and swimming pools. As well as this guide, it’s important to refer to the instructions and warnings that are on the products you are using. 

The 3 Simple Steps Guide

If you are setting up your new hot tub or spa, take a look at simple steps to get you started. 

Add commissioning or normal shock doses of chlorine

After you have filled your hot tub with water and before using it for the first time, you will need to add an initial shock dose, this will help to remove any bacteria and increase the time you have until the water needs replacing (in this time you will also need to regularly maintain the water with chemicals).

 

Test the water

You will need to wait for 24 hours, then you can test the water. You can use test strips to test the water and before you do this, make sure that the chlorine, pH and total alkalinity levels are balanced before using the hot tub. You may also need to adjust them before testing and the dosage amounts may vary.

Practice a regular maintenance procedure

To help you to maintain a healthy hot tub that is clean and healthy, we recommend that you start a hot tub cleaning and maintenance regime. You can list tasks that will need providing on a daily, weekly and monthly basis. One of the easiest things that you can do is to always test the water before you use your hot tub, you should then make the necessary adjustments to the chemical levels as and when you need to.

Your Chemical Care Routine

Daily Chemical Cleaning

As mentioned earlier, you should list and provide the necessary tasks and duties that you will need to carry out in your hot tub or spa.

Keep your filter on

We advise that when it comes to the hot tub water, it is filtered for a minimum of 4 hours a day, if you leave your hot tub on, the filter cartridge will collect any suspended dirt or oils.

Test chemical levels before use

You should always make sure that hot tub and spa chemicals are balanced. This is to maintain clean and healthy water. If your chemicals aren’t at the right levels, this could be the chlorine, alkalinity or pH levels, then your hot tub or spa won’t be functioning safely.

Check the filter cartridge

Filter cartridges should be removed and cleaned after every use, every few weeks or after the hot tub has had lots of use, you should replace the filter cartridge with a new one. You should also look out for discolouration or stiffness.

Check out our top tips of how you can clean your hot tub filter:

  • Make sure that your pump is switched off.
  • Remove the complete hot tub filter housing from the hot tub or spa.
  • Remove the filter housing and cartridge.
  • Wash the cartridge with the hose or cold tap water and then leave it to dry. Don’t use any detergents to clean the filter.
  • Next the filter will need replacing, do not use a wet filter cartridge as this won’t work properly.

Weekly Chemical Cleaning

Every week there are certain activities that you will need to provide in order to prolong the life of your Lay-Z-Spa’s water.

Shock dose if used often

Hot tubs are smaller in size than swimming pools, they will be shared by more people which means a lot more contaminants will be brought into the water. We recommend that you provide a shock treatment to the water once a week especially during frequent use. During periods of less use, the hot tub or spa may not need to be shocked as often,  but you will still need to keep an eye on the water quality, clear water doesn’t always mean clean water. 

Clarifier 

Clearwater clarifier, this includes flocculants that stick small particles of debris and algae together, this will make it easier for your spas filtration system to monitor the water and keep it clear.

Monthly Chemical Cleaning

Every month you’ll need to provide the following in order to maintain water hygiene.

Replacing the water

The amount of water changes will reflect the extent of use of the hot tub, this will also affect the chemical testing. If chemical levels aren’t at the usual ranges or if you seem to be losing a lot of water, it’s advised that you replace all of the water, retreat and retest again before use.

Impromptu Cleaning

This refers to particular chemical reactions in the hot tub water.

Foam Remover

We advise that you shower before using the hot tub, this is to help reduce the amount of residue from products including shampoo, deodorant, detergent, sun cream, make up, fake tan and any other natural boiler oils. All of these things can cause chemical imbalances, we know that showering may not be able to fully remove all of these substances and some that are still present may react with the water. To prevent this, you can use a foam remover in the water.
