To dose your hot tub ready for bather use, we advise using chlorine or bromine granules rather than tablets, which should be added only when your Hot Tubs pump is running. It is important to ensure your spa water is at a normal level of 3-5 parts per million (ppm) for free chlorine and 4-6 PPM for bromine before use.
You should put chlorine in your hot tub at least once a week. However, some people prefer to add a small amount after each use. Finding the best water care routine will depend on how often and how many people use it. Chlorine levels should be between 1.5 and 3.0 ppm.
Chemicals in your hot tub water can be a delicate balance. So it's crucial to maintain the levels of pH, Alkalinity, and Chlorine or Bromine, also known as sanitizers. You should wait 12 hours before entering the hot tub when you've added either chlorine or bromine to allow it to take effect properly.
While you could use a hot tub without chemicals, you could not soak safely. Water needs to be circulating and treated in order for it to be good for soaking. When you don't use chemicals in your hot tub or use too little, you are creating the perfect environment for algae, bacteria, and other contaminants to thrive.
So although you cannot run a hot tub without chemicals, you can run a hot tub without the harsh effects of chemicals with Silk Balance. Please note - you must drain your hot tub and flush out the pipes with Clean Start if you are switching your existing water to Silk Balance for the first time.
Essential oils aren't designed for use in hot tubs, so unfortunately they cannot be used inside a spa. These products can cause a myriad of problems to a hot tub's filtration system. Essential oils act the same way the oil that comes from our skin does, but more potent.
Chlorine tablets are a great way for you to keep your hot tub, pool, or inflatable spa clean throughout the year. They are a great choice because they have the ability to sanitize algae, bacteria, and other contaminants while also being affordable.
Generally it is recommended that you shock your hot tub once a week – more often if it's seeing heavy use. If your levels are all good, but the water is a bit cloudy or doesn't quite smell right, it's time for a shock. You should also shock the tub if you haven't used it for an extended period of time.
Green hot tub water can be caused by algae which is usually a sign of insufficient sanitisation level (Chlorine or Bromine) in your tub. Minerals such as iron, copper, and manganese can also make the water turn.
With average use, your hot tub should be drained and refilled about once every three or four months. But since everyone uses their hot tub differently, the answer can vary based on how many people use it and how often. Hot tub manufacturers like Jacuzzi offer some handy tips for figuring out when to drain and refill.
The primary culprit of foam is failing to sanitize your hot tub water weekly or after heavy use, such as a hot tub party. Lotions, cleansers, makeup and even laundry detergent leave our bodies and swimsuits when we soak in water. Foam will appear if the pH balance of your hot tub water is off.
Keep the water clean
Using chlorine or bromine sanitizers to kill the bacteria that grows in the water. You can also use mineral sanitizer with oxidizer and a little chlorine or bromine to make it effective. Always shower before entering the tub to get rid of body oils, perfumes, makeup and any other chemicals.
So, what is the ideal hot tub temperature when not in use? A good rule of thumb to follow is always keeping your hot tub's temperature 5 degrees below what it usually is.
You can use baking soda in your hot tub if its pH is too low. Baking soda can raise both the alkalinity and the pH of your hot tub and help it achieve the right chemical balance and stability. Its presence can also keep your tub from being cloudy.
While Epsom salt in the bathtub is OK, hot tubs and Epsom salt simply aren't a good combination. Pure Epsom salt has acidic properties that can disrupt the pH balance and total alkalinity of the water in your hot tub, which can eventually cause your tub equipment to corrode.
Regular hot tub shocking is inevitable to keep your water clean and safe for use. Dead skin and other elements like hair may end up dropping in the hot tub, leaving the tub in a mess.
A chlorine level of between 3-5mg/l must be maintained in your hot tub at all times. The addition of chlorine will depend upon usage and bathing habits. It could be daily or every 2-3 days (for 1mg/l add 2g per 1000 litres).
Regular household bleach (non-scented and without additives) can be used in a spa, but the pH level may rise as bleach has a very high pH of 13. For this reason many spa owners may find it easier to use dichlor (chlorine granules) or non-chlorine shock (MPS), which are more pH neutral.
How Long do Chlorine Tablets Last in a Hot Tub? Small 20g chlorine tablets will dissolve slowly over a period of 3-7 days depending on water flow, water temperature and hot tub usage.
While shocking and adding algaecide is effective in getting rid of algae, it should not be done together. This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM.
DO NOT mix chlorine and bromine together in either a dry state or within the water as this can cause a dangerous reaction. If you are considering switching from one sanitiser to another you should always clean and drain your hot tub including a line flush.
