Cloudy,
Dull, 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 color. 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.
