  • Who is the inventor of the SPA?
    1. Roy Jacuzzi
    2. Kanneth Spa

Answer:

The SPA was created by Roy Jacuzzi at the very beginning of the 20th century. He made several inventions: a new generation propeller, an irrigation pump for farmers, a hot air fan... When one of his children suffers from very painful arthritis, Roy Jacuzzi found an invention to reproduce the effects of hydrotherapy and designed a jet pump. A member of the next generation continues on the same path, and develops large baths with a heating system. It is from there that the improvements are made gradually until they reach the Jacuzzi.

  • The milky aspect of pool water is due to a presence:
    1. Of copper
    2. Of limestone

The water line is particularly prone to limescale deposits that retain fatty deposits and algae. To get clear water:

  • Check the stabilizer rate, if it is higher than 75mg/L, drain part of the basin.
  • Check the pH of the water, and set it at 7.0
  • Carry out an anti-limestone treatment: 1L/10m3
  • Leave the filtration running continuously 24 hours a day for 48 hours, rubbing the water line regularly
  • In case of persistent problems, carry out shock treatment

  • At what temperature should a cleaning robot not be used, in general? 
    1. Below 5° C
    2. Below 15° C

Answer :

Pool robots are designed for use in water temperatures from 15 to 35°C. Below 15° is not recommended. The low water temperature could shrink the plastic and cause water infiltration, which will weaken the robot's engine block, creating irreversible damage. The minimum operating temperature may vary depending on your robot. Indeed, tropicalized robots can withstand temperatures up to 5°. Refer to the instructions to be sure.

  • The ideal pH of the water should be between:
    1. 6.5 and 7
    2. 7 and 7.4

Answer:

Checking the pH of your pool or spa water is essential to have beautiful and healthy water. The pH should ideally be between 7 and 7.4. If the pH is too far from this level, here is what happens:

  • Discomfort of swimmers (irritating to skin, eyes, mucous membranes)
  • Premature corrosion of equipment
  • Promotes the appearance of algae
  • Decreases the effectiveness of the disinfectant (chlorine/bromine)
  • Decreases the efficiency of the flocculant

The factors that move the pH are:

  • The changing outdoor temperature,
  • A higher number of visitors to the basin,
  • External factors of pollution...
