How do I change from chlorine to a non chlorine sanitiser?

We usually advise if the water is over two months old it is best to dump it and start over.

If your water is under 2 months old please follow the instructions below:


Step 1. Clear the water

Water as supplied by the water authorities has chlorine included and so this needs to be eliminated if we are to have a chlorine free spa. Simply use a chlorine free sanitiser such as Popptis Spa Sanitiser and filter for 4 hours. This will oxidize the chlorine and any other unwanted matter in the water. Rain water and bore water also needs to be treated.

Step 2. Balance the water

Using a water test kit or strip, check the pH, alkalinity and calcium hardness levels of the water.

The pH should be around 7.4 – 7.6 to be comfortable for people with sensitive skin. Total alkalinity should be between 80 – 120pp. If necessary, adjust these two levels using a Water Balance to increase or decrease.

Calcium levels that are lower than 100ppm can be damaging to equipment, as well as making it difficult to maintain pH levels and ultimately cause the water to go cloudy.

Rain water is usually low in calcium. Ideal levels for calcium hardness are between 100 and 200 ppm. To increase calcium levels use Calcium Increaser as per label directions.

Step 3. Sanitise the water

The water is now clear of contaminants and balanced, all that needs to be done is to sanitise the water with chlorine free sanitiser - Conditioner, bactericide and clarifier as per label directions.
