MEGADIN Huwa-San for swimming pools

(1) After cleaning the pool, adjust the pH value. Always maintain between 6,8 and 7,2 (weekly control). In order to reduce the pH value by 0,2 points, add 150 gr. of MEGADIN pH MINUS per 10 m³of water.

(2) Switch on the circulation installation and add HUWA-SAN O₂ to the desired area or use the dosage System (about 4-5 litres per 50 m³ of water = 80-100 mg/l.).

Measure the concentration of the product by means of HUWA-TEST measurement strips, and grade between 70 and 100 mg/l on the colour scale.

It is important that the value of the scale is not below 50 mg/l.

(3) For the complete disinfection of the sand filter, it is recommended to slowly add 0,2 ltr of HUWA-SAN O₂ to the skimmer (once a week) during circulation.

(4) For optimum filtering efficiency and elimination of organic dirt, slowly pour 2 or 3 cups of 0,2 ltr FLOCK FEIN powder into the skimmer during circulation, after every filter rince (once per week).

(5) Should algae appear despite the treatment carried out according to the instruction, it is necessary to add 1 litre of HUWA-SAN O₂ per 10 m³ of water to the desired place in the pool (the measurement strip will indicate 100 mg/litre). It is important that water circulation should continue until the algae have disappeared.

Warning:

Important: At the beginning of the treatment, circulate the water of the pool twice.

For example:

Pool content: 50 m³

Filter yield: 10 m³/h = 10 hours of operation!

Thereafter the normal filter circulation time ranges from 6-8 hours daily.

Continuous dosage: (a 50 m³pool)

If the concentration of the products has decreased to 50 mgr/ltr, add 1 to 2 litres of HUWA-SAN O₂ to the water and keep stirring it for at least 2 hours.

Average expense: in a private pool, with water under normal conditions, it will be 1 litre per 1 m³ a year.
