Pool Opening Chemical Treatment

Days
Treatment
1
On the First Day you need to follow instructions below:
• 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
Add Unstabilized Liquid Chlorine: add 1 L of liquid chlorine per 10,000 L of pool water. Test after 10 minutes: if levels are below 1.0 ppm, repeat until 1.0 ppm is obtained.

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.
