How to switch from spa chlorine to a chlorine free spa sanitiser

We get this question quite a bit:

How do I switch my spa from lithium spa sanitiser to a chlorine free spa sanitiser?

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

If it is under that then all you have to do is follow these instructions if you are using Poppits chlorine free sanitiser.

START UP PROCEDURE:

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 Poppits Quick Fix at the rate of 60 grams per 1000 litres of spa water and filter for 4 hours. This will oxidise 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 test 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 Poppits Water Balance to increase the level or Poppit pH Decreaser to reduce them.

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 predictably low in calcium. Ideal levels for calcium hardness are between 100 and 200 ppm. To increase calcium levels use Poppit Spa calcium increaser as per label directions.

Step 3. Sanitise the water

The water is now clear of contaminants and balanced and all that needs to be done is to sanitise the water with Spa Poppit - Conditioner, bactericide and clarifier at the rate of one litre per 1000 litres of spa water.

It’s that simple!
