Keep your spa clean and healthy throughout Winter with our simple maintenance and water balancing tips so your spa is ready to go when you are!

One of the main things to look after your spa is knowing how it works. Having a good knowledge of the features will ensure not only that you get the most from your spa, but you also know how to deal with any potential issues if/when they arise.

Water Balance

Keeping your spa water balanced is vital to keeping your spa healthy. This involves tracking the same elements as a pool: pH, alkalinity, calcium and sanitiser levels, etc.

If you’re just filling your spa with fresh water, you’ll need a shock dose to begin. Either a non-chlorine Shock such as Spa Pro Spa Shock or Poppits Quick Fix or chlorine/bromine (according to dosage instructions on the container) will do the trick. Then balancing the Alkalinity, hardness, pH & sanitiser will follow. Use your test strips to determine your balances then adjust accordingly with the relevant chemicals and the dosage rates on the container.

The Alkalinity of your spa water needs to be maintained between 60 -120ppm in your spa for a few reasons. The first is it helps regulate your pH and keep it more consistent, therefore helping your sanitiser work better. When within the ideal range, it also helps reduce scaling on the surface of your spa. Increase your spas Alkalinity with Spa Pro Alkalinity Increaser as per the dosage rates on the container.

Calcium is also important for water balance, too low and the water becomes corrosive and too high and it shifts to being scale forming as it seeks the balance it needs. Try keeping it between 200-300ppm

Aim for a pH level that sits between 7.2 – 7.6. balancing your water with alkalinity and hardness is usually sufficient to raise the pH and will not only keep you comfortable but also protect your surfaces and equipment. Equally, if you find your water is too alkaline, (pH above 7.6) use Spa Pro pH Reducer to prevent cloudy water and prevent scale build-up.

Bromine is the more commonly used sanitiser in spas of which the level should be around 3.0 – 6.0ppm. If you using a non-chlorine-based sanitiser such as Aquaspa, 15ppm is ideal or Poppits 60-100ppm and finally Perox395 60-80ppm

As warm water is a great environment for nasties, it’s important to keep it safe for you and your family with regular testing to ensure your sanitiser level is high enough. If it’s low, add your preferred sanitiser according to dosage instructions on the container.

It’s also a good idea to shock your water after a period of inactivity or if the water is cloudy or there is an odour. A shock treatment with Spa Pro Spa Shock will ensure the water is completely sanitised before you jump back in.


By keeping the water flowing through your filter, it will help keep your spa free of contaminants. The more you circulate your water through the filter, the cleaner it will be!

The hot water in your spa extracts the oils and lotions from your skin, so a quick rinse in the shower first before getting into the spa will make things easier on your filter!

Weekly brush

A spa is prone to developing grime around the waterline, so a quick weekly scrub with a brush, while the filter is running, should remove any dirt, grease, or stains and keep your surfaces clean.

Giving your filter a clean using a liquid cleaner such as Spa Pro Filter Cleaner & Degreaser or Poppits filter cleaner every month or so will increase the efficiency of your filter which in turn will reduce your overall maintenance cost.
