Troubleshooting
Below are common problems you’ll find in pools and
recommended solutions.
Please note: In all cases, taking a water sample to your BioGuard® dealer for analysis is the best solution.
Algae
Definition / Cause
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.
Solution
Black Algae
Definition / Cause
Forms in cracks and crevices on pool surfaces, especially plaster finishes. Known for protective coatings that make it impervious to normal chlorine levels.
Solution
Chlorine Residual
Description / Cause
The most common cause of increased chlorine demand is a high level of contaminants.
Solution
Cloudy Water
Definition / Cause
Hazy, murky appearance. Caused by poor filtration, inadequate circulation, water balance, low sanitizer levels and/or lack of routine oxidation.
Solution
Foam
Definition / Cause
Foam is caused by elevated levels of algicide or a foaming algicide in pools with jetted returns, attached spas or water features
Solution
Mustard (yellow) Algae
Definition / Cause
A chlorine-resistant form of green algae. Often
resembles dirt or sand on bottom or sides of pool.
It can be brushed away very easily, but returns
quickly. Although it can create a large chlorine
demand, it has been known to survive in high levels
of chlorine.
Solution
Scale
Definiton / Cause
Scale formation is caused by high calcium hardness.
Solution
Staining
Definition / Cause
Discoloration of pool equipment and surfaces caused by contamination, sunlight and metals in pool water.
