Hot tub how much chlorine

Our hot tubs chemical guide can help you choose the right sanitiser for you. When a hot tub has been refilled, it is important to give the water a high dose of sanitiser. 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 parts per million ppm for free chlorine and PPM for bromine before use.

You should regularly check that the filtration system is in good working order. It is important to note that when your hot tub cartridge filter is dirty, the performance of your filter will deteriorate leading to dirty and potentially contaminated water. Usually, spa cartridges will need cleaning weekly depending on use , however, we would advise more regular cleaning if your hot tub is being used a lot, or the risk of contamination is high e.

This allows you to make any appropriate chemical adjustments that may be required. We advise any hot tub owner to test their water daily whether the spa is in use or not, due to warm water requiring sanitising regularly.

When using any test strips, it is important to follow the instructions on the bottle carefully to get the most accurate reading.

After you have been testing your hot tub conditions for a while you will become aware of how refilling, topping up, adding chemicals and general usage will affect the readings and chemical levels. There are several main elements to maintaining your hot tub water. Some basic tips are shown below, and you can read our detailed guides on each section for more information. A Master Spas customer recently reached out, asking about how to increase the chlorine level in her swim spa.

We have also noticed that the walls are slimy and the floors are slimy. Routine water care is key to avoiding hot tub water problems. However, changes in how many people are using the spa, how long people are soaking, and other factors can affect the chemical levels of your spa.

Master Spas recommends testing the water before you use it to make sure that the water is safe to get in. People should not get in the spa if the chlorine levels are out of range. Your total chlorine should be between 2 and 4 ppm.

When you are finished enjoying the hot tub or swim spa, treat the water to maintain proper pH and chlorine levels. Oftentimes, you can add a sanitizer, like sodium di-chlor, and let the jets run for 15 minutes.

It can be frustrating to treat your swim spa or hot tub water only to see your chlorine levels keep dropping. But before you add yet another capful of chlorine to your hot tub, be sure to take measures to target the underlying cause. Not all hot tub and pool chlorine products are created equal. Our hot tub chlorine granules and tablets are of the highest quality, which means you will require smaller amounts to achieve healthy water than cheaper alternatives. When hot tub chlorine is dissolved in water it creates hypochlorous acid which reacts with bacteria in the water, breaking it down and killing it in the process.

During this process the hypochlorous acid molecules will react with other elements and become deactivated, which is why constant maintenance is required. The addition of chlorine will depend upon usage and bathing habits. When performing the weekly maintenance, it is important to ensure the pumps are running and the hot tub is uncovered. If possible, try the methods mentioned above before using a neutralizer.

It is recommended to try natural methods first to avoid any chemical staining to the shell. The most common neutralizer is Sodium Thiosulfate. When adding this chemical to the spa, it is important to first read the instructions and add it very gradually. As mentioned above, addition or depletion of chlorine can affect other chemical levels in the spa. So, after the tub has been adjusted, use test strips to make sure other chemical levels are in check.
