If algae have invaded your pool water, it is most likely due to a lack of chlorine and the presence of phosphate. No worries, the AZUR brand offers simple and effective solutions that will restore your water’s crystal-clear appearance in no time.

 

Lack of chlorine

 

The chlorine level in a swimming pool must be at least 1 ppm and at a maximum of 3 ppm. If you run out of chlorine, you will quickly get algae, especially in hot weather.

 

It is therefore important to have a minimum of 1 ppm of chlorine in your pool water, 24 hours a day, 7 days a week. We even suggest 2 ppm at any time. In the presence of chlorine, algae will not be able to proliferate.

 

As a preventive measure, we also recommend that you use 60% DESTRUCTIVE ALGAECIDE in small doses each week (25ml of 60% algaecide per 10,000 litres of pool water). This way, if you run out of chlorine, the algae will not be able to proliferate, as there will be an algaecide in the water.

 

Here is the method to eliminate existing algae:

 

  1. Add 250 gr of TURBO SHOCK per 10,000 litres of pool water directly into the skimmer;
  2. Wait 5 minutes;
  3. Add 100ml of 60% DESTRUCTIVE ALGAECIDE per 10,000 litres of pool water.
  4. Wait 3 hours then scrub the sides and the bottom. Wait another 12 hours then vacuum. Follow by a backwash.

Presence of phosphate

 

Phosphate is the main food for algae. Without the presence of phosphate, algae will have difficulty proliferating. To determine if phosphate is present, simply visit your local pool centre to have your pool water tested.

 

With a high phosphate content (over 1000 ppb), algae will be able to grow despite the presence of chlorine.

 

Fortunately, there is a product that removes phosphate. It is found under the name PHOSPHATE REMOVER. If a water analysis detects the presence of phosphate, follow the following table:

DOSAGE PER 10 000 L. OF WATER

PHOSPHATE LEVEL PPB 

300 or less

600

900

PHOSPHATE REMOVER

125 mL

250 mL

375 mL

In order to maintain clear and sparkling water during the swimming season, make sure to have your pool water analyzed regularly by your specialized retailer to adjust and maintain the following parameters: total alkalinity, calcium hardness and stabilizer. Ideally, the week following the opening of your pool, in early June and late July.
