Insufficient chlorine levels maintained below 1ppm and bacteria introduced by bathers
and the environment is the main cause of eye, skin and nose irritation.

Hazy, murky appearance. Caused by poor filtration, inadequate circulation,
water balance, low sanitizer levels and/or lack of routine oxidation.

Forms in cracks and crevices on pool surfaces, especially plaster finishes.
Known for skeletal growths that make it impervious to normal chlorine levels.

A common “green” algae that can be free floating or wall-clinging. Ranges in severity from
patches on walls and bottoms to entire pools. Can clog filters and create surface damage if left unchecked.

Clear green water (limejuice colour) is caused by corrosive water conditions,
low pH and low total alkalinity. Discoloration of pool surfaces and equipment is
caused by contamination, sunlight and metals in pool water.
