A guide to sanitising your spa

Reading time: 2:30 –

When it comes to treating your spa, sanitiser is your best friend!

It’s the product that will keep your water clean and healthy by destroying any bacteria that develops. Bacteria thrive in a warm moist environment, so the hot water of your spa is the perfect breeding ground. By ensuring that there’s sufficient sanitiser continually present in the water, your spa will be safe every time you use it.

There are a variety of spa sanitisers on the market which can make choosing one confusing but to keep the water safe for you and your family, you want to ensure you’ve got the best! Chlorine and bromine are the two main chemicals that are recognised by Health Authorities as providing the necessary level of safety for bathers. That’s why we make all of our sanitisers with either chlorine, bromine, or a combination of the two.

Maintaining your spa’s sanitiser dosage is vital to keeping all bathers safe. Thankfully, doing so is relatively simple!

Treat it right

At the start of the season, we recommend taking a sample of your spa water to your local BioGuard Approved Retailer for a professional state-of-the-art water test. From then on, test your water at home at least once a week, to maintain an active level of sanitiser throughout the season. You want the sanitiser level to sit around 2-5ppm bromine or 1-3ppm chlorine. If the level drops below the recommended range, bacteria will begin to grow and multiply quickly. If the level has dropped, add the recommended dosage of your sanitiser to the water (dosage rates differ for spa baths and outdoor spas/hot tubs). Along with your weekly sanitiser routine, it’s also a good idea to regularly shock your spa during the season. Doing this will destroy any build-up of contaminants in your water.

Not sure which sanitiser best suits your needs?

Indoor spa or pool with attached spa

BioGuard SPA Symmetry® is the ideal product to sanitise your indoor spa, or pool with an attached spa, due to its reduced odour. It consists of a mixture of bromine and chlorine, and when used as directed, its slow, consistent dissolving rate provides a constant and reliable sanitiser level at all times.

Outdoor spa

For an outdoor spa, use BioGuard SPA Armour®. It’s fast-dissolving so you can add it straight into your spa, and its dual action acts as both a sanitiser and oxidiser. Keeping not only your water clean but also clearing cloudy water.

If you’re unsure about the sanitiser dosage rate for your spa, visit your local BioGuard Approved Retailer for expert advice.

Quarterly deep clean

It’s also important to note that your spa should be drained every quarter. It will need a deep clean to cut through any stains or biofilm build up (biofilm harbours bacteria). For this, add a dose of BioGuard SPA Swirl Away®, turn on the pump for circulation, drain the water and then refill with fresh water.

Keeping your spa water sanitised isn’t rocket science. Keep on top of your treatment, and you can soak all season!
