BioGuard – Troubleshooting

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

  • Banish®: Kills all types of swimming pool algae
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

  • Banish®: Kills all types of swimming pool algae
  • Spot Kill®: Formulated to kill black algae on walls.
  • Spot Kill WP: Only used on white plaster pools.
Chlorine Residual

Description / Cause

The most common cause of increased chlorine demand is a high level of contaminants.

Solution

  • Burn Out Extreme® or Burn Out 35: Corrects chlorine levels
  • Take a water sample to your BioGuard Dealer and let them perform a test to help
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

  • Lo ‘N Slo®: Corrects high pH
  • Strip Kwik® or NEW improved Kleen It®: Cleans dirty filter media
  • Burn Out Extreme® or Burn Out 35: Boosts sanitizer levels
Foam
Definition / CauseFoam is caused by elevated levels of algicide or a foaming algicide in pools with jetted returns,  attached spas or water features.  Foaming can also be caused by a foreign contaminant such as soap or oil entering the pool.  Foam should dissipate over time, but the use of AntiFoam will help clear the foam much more rapidly.

Solution

  • Anti-Foam: Eliminates foam quickly
  • To prevent foam from occurring due to high algicide levels, skip your next scheduled addition of Back Up® or switch to non-foaming Algae All 60®
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

  • Banish®: Kills all types of swimming pool algae
Scale

Definiton / Cause

Scale formation is caused by high calcium hardness.

Solution

  • Scale Inhibitor: Eliminates scale discoloration. Helps prevent scale from forming on pool surfaces and damaging the equipment
Staining
Definition / Cause

Discoloration of pool equipment and surfaces caused by contamination, sunlight and metals in pool water.

 

Solution 

  • Stain Remover: Removes most stains from pool surfaces and returns all metals to pool water
  • Pool Magnet® Plus:Ties up metals in pool water
  • Sparkle-Up®: Aids physical removal of metals through filter
