Below are some common problems and recommended solutions. Please note: In all cases, it is best to bring a water sample to D & D for a free analysis and printed report.

Algae– 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: BioGuard Erase – Kills all types of swimming pool algae.

Black Algae – Forms in cracks and crevices on pool surfaces, especially plaster finishes. Known for skeletal growths that make it impervious to normal chlorine levels. Solution: BioGuard Erase – Kills all types of swimming pool algae.

Chlorine Residual – The most common cause of increased chlorine demand is a high level of contaminants. Solution: BioGuard Burn-Out Extreme or Breakpoint 35 – Corrects chlorine levels (bring a water sample to D & D to help determine the right amount of shock needed).

Cloudy Water – Hazy, murky appearance. Caused by poor filtration, inadequate circulation, water balance, low sanitizer levels and/or lack of routine oxidation. Solution: BioGuard Lo ‘N Slo – Corrects high pH. BioGuard Filter Brite – Cleans dirty filter media, BioGuard Burn-Out Extreme or Breakpoint 35 – Boosts sanitizer levels.

Foam – Caused by elevated levels of algicide or a foaming algicide in pools with jetted returns, attached spas or water features. Solution: BioGuard Anti-Foam – Eliminates foam quickly (to prevent foam from occurring due to high algicide levels, skip your next scheduled addition of Bioguard Back Up or switch to non-foaming BioGuard Banish.

Mustard (yellow) Algae – 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 chlorine demand, it has been known to survive in high levels of chlorine. Solution: BioGuard Erase – Kills all types of swimming pool algae.

Scale – Formation is caused by high calcium hardness. Solution: BioGuard Scale Inhibitor – Eliminates scale discoloration. Helps prevent scale from forming on pool surfaces and damaging the equipment.

Staining – Discoloration of pool equipment and surfaces caused by contamination, sunlight and metals in pool water Solution: BioGuard Pool Magnet Plus – Ties up metals in pool water and can remove fresh stains, BioGuard Kwik Clear – Aids physical removal of metals through filter.
