Having a hot tub where you can soak and relax – while jets massage your muscles and rid them of their aches – and you forget all those worries that drove your stress level over 10 is an amazing thing.
Hot tubs do require some maintenance and must always be kept clean so you can ensure that it never has or grows bacteria that can be life-threatening if you’re exposed to it in the right way. The water in a hot tub must be balanced so that no algae can grow in it. All this is easily possible if you use the right hot tub chemicals that are meant specifically to keep the water in the tub in the condition that it needs to be to ensure it’s cleanliness and safety.
Unlike a bathtub you do not drain the water from a hot tub after you have used the tub. Water in hot tubs can stay in a tub for weeks if not months, and unless this water is sanitized with chemicals, it could become an incubator for bacteria and organisms that may not be healthy for you to soak in. It is not enough to just vacuum the tub once in a while and keep the debris out of it, as then its use can lead to illnesses that are related to hot tubs. You can prevent any issues by using the appropriate hot tub chemicals in the correct quantity and at the right time.
So, what are the chemicals that you will need for a hot tub and what are the quantities that you must use to balance and sanitize your hot tub water? You will do this correctly if you first know the quality of the water that you are using and subject it to testing with a proper test kit or test strips, that you would do well to have a proper stock off, once you have purchased and set up your hot tub. Or even easier, bring a water sample into the FORM hot tub showroom and our testing machine will tell you exactly what to do to make your water the most comfortable and safest it can be. Once you have the readings of your test, it becomes easier to determine the chemicals you need and the amounts that are just right for your water.
The most important hot tub chemical that you can use is the one that keeps the water in your hot tub properly sanitized. This can be chlorine, bromine, biguanide, minerals or a salt system. Chlorine is the most common as well as being cost-effective. It is an aggressive killer of algae and bacteria and is easy to manage and add. A proper chlorine level in hot tub water is between 1 and 3 parts per million.
Bromine is also another chemical that is commonly used and works in a different way from chlorine. Its pH is lower than that of chlorine and this makes it easier to keep the water balanced. It is also gentler on the skin and can last longer. It is slow-acting. Biguanide is a sanitizer that contains no chlorine, does not require frequent use, is odorless, and makes the water smoother. But the higher cost can be a deterrent. Levels need to be between 30 and 50 ppm.
Silver can act as a mineral bactericide, while copper can kill algae. The use of minerals makes water that is less harsh on your skin, but it may not be enough to sanitize the water and will need the addition of some chlorine. Their costs can also be high but they are very easy to manage. Saltwater systems convert salts into chlorine that then sanitizes the hot tub water. You would need to buy a device that is a salt-chlorine generator.
Even if you keep your hot tub water properly sanitized, it will still benefit from a shock a few times a month. The amazing pressurized filtration systems in our Coast Spas helps to keep dirt, oils and organic materials out of the hot tub water which can help reduce the quantity of chemicals that are needed in your tub. pH levels do need to be maintained below 7.6 and this can be done by adding salts that can decrease the pH or others that can add to it if necessary.
