Biocides and You

Biocides and You

Here at SpaChem™, customer sanctification is our top priority. We aim to ensure that you not only enjoy your hot tub, spa, or pool but also understand the ‘hows’ and ‘whys’ behind each of the products that you use. 

From this drive, our SpaChem™ FAQ series was born. Here, we start off with the cornerstone of your water health and safety management plan – biocides. 

What is a Biocidal product? 

By definition from the Health and Safety Executive, a biocidal product is one that controls harmful or unwanted organisms through the use of chemical or biological means. A biocide can be synthetic or derived from a natural source. 

So, what does this mean for you? Biocides can be found in a wide variety of everyday household products including antibacterial soaps, kitchen or bathroom cleaners, and even insect repellent. They have become part of modern life and are key to you and your family’s health and safety. 

They are also essential to guarantee the hygiene and cleanliness of your pool, spa, or hot tub. Here at SpaChem™, we have developed a range of biocidal products that utilize oxidizing biocides such as bromine or chlorine. These disrupt normal enzyme behavior and destroy cell walls, causing microbes found in water to die. Checking for the free levels of chlorine and bromine along with pH and total alkalinity is essential to maintaining a healthy hot tub spa or pool. By allowing the biocide level to drop below an optimal range, you will allow bacteria and microbes to multiply. 

Useful tip: Bromine and chlorine levels should be checked daily with the use of either 3-in-1 or 6-in-1 testing strips. 

So, which should you use – bromine or chlorine? Over the coming weeks, we’ll be discussing topics such as this and others to ensure you have all the information you need to maintain a healthy spa, hot tub, or pool environment.

In our next post, we explore chlorine and why it has become one of the most popular and widely available water treatment biocides. In the meantime, we are always here to answer any questions you may have. Visit us at for our entire range of pool, spa, and hot tub products.
