• Add Stain and Scale Control by pouring it slowly around the perimeter of your pool water. Chemical dosage is 100ml per 10,000 L of pool water.
• Wait for 3 hours then shock your pool with non-chlorine based Oxidizer. To shock your pool add 1 Kg per 75,000 L of pool water
• Check your pool chemistry and balance all chemicals:
  o pH: 7.4 – 7.6
  o Calcium hardness: 200 – 350 ppm
  o Total alkalinity: 80 – 140
Install your Nature II cartridge if applicable. You need to do this every season.
• Establish the recommended sanitizing level by applying an unstabilized granular or liquid chlorine.

Add HTH Extra: broadcast 65g per 10,000 L. Test after 10 minutes, and if levels are below 1.0 ppm, repeat until 1.0 ppm is obtained. OR

On Second Day you need to follow instructions below: • Add 40% Algaecide by slowly pouring it around the perimeter of the pool water. Chemical dosage is 100mL per 10,000L of pool water. Wait 1 hour to let circulate. Make sure chlorine level is 1 to 3 ppm. • Turn on chemical feeder to its medium setting. Wait for 24 hours and conduct a test on your pool water. Adjust your chemical feeder output as required.


In case of:
a) Nature II Pools: Circulate the pool 24 hours for the first 4 days with a chlorine level over 1 ppm. After day 4 allow the chlorine level to drop to 0.6 ppm. At this point, your pool should circulate no more than 12 hours a day.

b) Bromine Pools: Once water is balanced you begin to start up the automatic brominating system. You must dissolve 25 grams of bromine per 10000 L per day for real sanitation.
