Why Is My Salt Water Pool Cloudy?In Feburary 2016 26,

Heavy use, such as hosting a pool party, can lead to cloudy water in your pool. Sunscreens, soaps, shampoo residue and other foreign substances can build up in the pool and cause the water to lose its sparkling clear appeal. Although a saltwater system uses a chlorinator to transform the salt in the water to low levels of chlorine, a higher dose may be required to burn out these elements. Using a chlorine shock treatment after heavy use will likely take care of the problem.
Dirty Filter
Pools keep debris and other impurities out of the swimming area by sucking the water through the skimmer and into a filtration system that traps the impurities in sand or another filtration device. This process is identical to the one used in freshwater pools. When the filter becomes clogged and dirty, it is unable to filter out all of the impurities and allows much of it to reenter the pool through the plumbing, which can cause the water to get cloudy. Backwashing is the solution to this issue. Backwashing means reversing the pump and causing the water to wash back through the filter where it ejects the impurities from the pool through an outlet on the exterior portion of the pool.
pH and Alkalinity
If your pool's pH level is not within the acceptable range, the water can become too acidic and become cloudy or dull. The same applies if the alkalinity of the pool is not within the preferred parameters. According to the GLB Pool and Spa website, a saltwater pool should be tested regularly for pH levels and should be maintained within the range of 7.2 and 7.8 on your test strips or water testing kit. Using pH up or down additives will adjust the pH as desired. Alkalinity should be between 80 and 120 parts per million.
Algae
While algae is not as much of a concern in saltwater pools as in freshwater pools because the salt does not provide a friendly growing environment for the algae, it can occasionally be a problem. Algae can cloud water or even turn it green. Lots of algaecide products are on the market to control this problem.

How to Make a Cloud in a JarIn Feburary 2016 02,

In Feburary 2016 02,
Tape a section of black paper to the back of a jar, leaving about half of the jar uncovered as a window to the interior. The dark surface will make the small cloud more visible when it forms.
Pour about an inch of hot water into the jar. Use a jar that is already at room temperature or above to prevent thermal shock from cracking the glass.
Swirl the water in the jar to warm the sides of the vessel and wash away any immediate condensation.
Upend the lid of the jar and use it as a shallow dish for the ice. Fill the lid with ice and set it atop the jar's opening.
Strike a match and blow it out. Quickly lift the lid from the jar and toss the spent and smoking match into the jar, then replace the lid.
Observe the interior of the jar and look for water vapor to condense into wisps of cloud on the smoke particles from the burnt match. Use a flashlight to illuminate the inside of the jar if the tiny clouds seem hard to see despite the black paper backing.
