We recommend shocking your hot tub before first use, anytime the water is replaced, after periods of heavy use, at signs of slime or algae or after a loss of clarity or water quality. Chlorine is the most popular choice amongst hot tub users as it is the most cost effective and fast acting sanitiser available. Chemical levels in your hot tub can be impacted by different causes and results vary with each situation. Chloramines (combined chlorine) are gassed-off pollutants in the water that give a hot tub that pungent chlorine smell.

However, one issue with tablets that some hot tub owners have is that it can be hard to boost chlorine levels with tablets as they are in set doses. The downside is that it contains CYA, which will cause the CYA levels in your tub to go up the more you use it.

By adding chemical treatment to the water, bacteria and algae growth is prevented (or rather, they’re killed off very quickly). If your spa already has bromine in it, every time you add shock (whether chlorine or non-chlorine), this existing bromine will get reactivated, and you will still have a bromine spa.You can usually control how much water comes into contact with the tablets, and therefore how quickly they dissolve. However, this has its own risks as not enough chlorine could be dissolving into the water as needed.

Every attempt should be made to avoid mixing spilled material with other chemicals or debris when cleaning up. Storing chemicals requires careful attention to the product label instructions for each individual product. It’s also important to note that there is no definitive answer to how often you’ll need to change the water in your hot tub, even if you are using chemicals.From the dos and don'ts to my personal favorite bromine hacks, you'll have all the knowledge you need to start using bromine effectively and safely in your spa.

Over time, the chemicals will react with the wood, causing grey-scale (where small grey flakes will come off the wood and end up in the bathing water) and ultimately decaying the structure of the wooden hot tub.

Balanced Total Alkalinity helps control the pH levels and the correct level to aim for is between 80 and 120 parts per million (ppm).We link primary sources — including studies, scientific references, and statistics — within each article and also list them in the resources section at the bottom of our articles. If you are going away we would suggest emptying the hot tub and cleaning it so the water is not left to go stagnant. Lithium hypochlorite is a granular shock with 28% to 35% chlorine, but it’s rarely available anymore due to the increasing demand of lithium for battery production.
