POSSIBLE PROBLEMS AND THEIR ELIMINATION

Eye and skin irritation and chlorine smell 

Reasons: 

• pH too gigh or too low
• presence of chloramine caused by organic waste combined with loose chlorine

Solution:

• measure and adjust pH (pH+ nebo pH-)
• shock chlorination (Chlor Chock) eliminates combined Cl and changes it to loose Cl

Rate of residual loose chlorine is rapidly decreasing

Reasons: 

• frequent use of pool in stormy weather (high air temperature)

Solution:

• shock chlorination (Chlor Chock), fill in Stabilizator Cl

Calcite sediments

Reasons: 

• pH is too high, calcite hardness is too high

Solution:

• measure pH and adjust (pH- )

Metal pieces corrosion

Reasons: 

• pH is too low

Solution:

• measure pH and adjust (pH+)

Sedimentary or milky water

Reasons: 

• insufficient filtration flow
• total amount of solid decays is too high
• pH is too high
• thick organic waste

Solution:

• check filtration, perform backward washing
• dose flocculant (Floculant) to speed the process
• empty 1/3 to 1/2 water in pool and replace it with fresh water
• shock chlorination (Chlor Chock)
• change sand filling if it is older then 2 years

Green and sedimentary water, slippery walls

Reasons: 

• presence of algae

Solution:

• measure pH and adjust if necessary (pH+ nebo pH-)
• use AntiAlgen (or Antialgen S)
• shock chlorination (Chlor Chock)
• if necessary, repeat shock chlorination up to 24 hours
• leave filter on constantly, wash and rise regularly
• if water is still sedimentary, read paragraph about sedimentary and milky water

Clear but coloured water (black, brown, green or pink)

Reasons: 

• metalic impurities such as copper, ferrum (iron) or manganese oxidizes in water

Solution:

• measure pH and ajust to 7,8 (pH+ nebo pH-)
• treat water with flocculant (Floculant)
• restore pH to ideal zone: 7,2 - 7,6
• shock chlorination (Chlor Chock)
• use preparation against ferrum (iron)
• repeat treatment if necessary

Foamy surface

Reasons: 

• excessive concentration of algicide

Solution:

• empty water partially and dilute with fresh water, until water stops foaming
• lower the algicide dosage

Black and felt-like stains

Reasons: 

• presence of black algae spravwilng on bottom and on walls

Solution:

• black algae are very resistant!!!
• check pH and ajust (pH+ nebo pH-)
• use AntiAlgen
• after 24 hours shock chlorination (Chlor Chock) and repeat every 24 hours
• clean affected places with brush
• if black stains are still visible after 3 - 4 hours days of treatment, lower the water level in a way that you can brush stains with 15 % clorine solution
• do not forget, that chlorine can discolour (burn) the foil

Heating not heating 

Reasons: 

• bad water flow

Solution:

• clean skimmer and hair filter (you can read how to clean hair filtere here)
• wash and rinse sand in filtration (you can read how to wash sand here)
