The most frequent problems and troubleshooting

Problem
pH value difficult to adjust
Cause
Alkalinity of water is too high
Solution
Measure the alkalinity of water, in needed adjust pH adjustment

Problem
Lime scale is formed in the swimming pool and on the equipment
Cause
Too high pH value of water or too high content of calcium.
Solution
Too high pH value is reduced using pH agents. If the content of calcium is too high, add soft water. Do not use chlorine preparations containing calcium. Use Melpool CAL, which prevents the depositing of lime scale.

Problem
Smell of chlorine as well as skin and eyes irritation.
Cause
Improper pH level
Solution
Control water and if need be, adjust the pH level.

Problem
Free chlorine disappears very fast
Cause
Too low amount of free chlorine, intensive swimming, high pollution level and high temperature
Solution
Shock disinfection using chlorine, use of chlorine stabiliser

Problem
Corrosion attack
Cause
Too low pH level
Solution
Increase pH level using PH+

Problem
Growth of algae, turbid water, green water
Cause
Too little chlorine or too high pH value
Solution
Balance the pH value Use shock chlorine disinfection, add flocculation agents, vacuum the bottom and add algaecides

Problem
Turbid water
Cause
Growth of algae
Too high pH level
Not satisfactory cleaning
Too high content of calcium
Solution
Use shock chlorine disinfection
Balance the pH value
Check the pump and the filter. Start the pump at “CIRCULATE” setting and check the current strength. Perform filter backwashing.
Replace at least one third of water with soft water. Do not use chlorine preparations containing calcium.

Problem
Swimming suits become faded
Cause
Chlorine overdosing
Solution
Add agents which reduce chlorine content or add fresh water.

Problem
Water is brownish or blue-green
Cause
Too high content of iron or copper.
Solution
Flocculation. Add Melpool CAL. In the worst scenario, replace half the water.

Problem
There is foam in the swimming pool
Cause
Overdosing the algaecide
Solution
In the next two weeks, do not add this agent. After that, dose the agent as recommended.

Problem
A black strip along the waterline.
Cause
Pollution, manganese
Solution
Lower the water level and clean the dirt using a brush and Melpool GEL agent.
