Cloudy, Dull or Hazy Water

 Suspended micro particulate matter, interfering with the passage of light is known as turbidity. It can range from an almost imperceptible haziness to a pure, milky white colour. Besides being unattractive, cloudy water can prevent the rescue of swimmers in trouble and may provide no depth perception for those who would dive into the water. This particulate matter also interferes with the ability of the filter and chemicals to properly sanitize the water.

This particulate matter can be carbonates and sulfates forced out of solution by imbalanced water, perhaps worsened by the introduction of high temperatures. The situation could also be the result of poor filtration and sanitation programs. It can indicate a problem with the effectiveness of the filter or the amount of time its allowed to run each day or it may point to sanitizer residuals being too low or inconsistently applied. Finally, cloudy water may result from pool water which has reached saturation. High TDS levels may not permit any more solids from being dissolved or saturated into solution.

Use of clarifiers, or chitin products such as Sea-Klear work to coagulate smaller particles into larger, filterable clumps. Use of these products are a helpful boost to your sanitation and filtration program, and are especially necessary in pools with undersized or inefficient circulation/filtration systems.

For extremely cloudy pools, shocking with lithium or sodium hypochlorite, followed by constant filtration with the use of clarifiers may be the best solution to the problem. If not, you may want to drain some of the water and dilute with less saturated fill water and / or use a flocculent to settle suspended material to the bottom for vacuuming.
