As more and more chemicals are added to pool or spa water, the inactive chemical ingredients accumulate and remain dissolved there. As water evaporates, the dissolved solids become more noticeable by clouding the water. When filtration and chemical levels are ideal but the water has a dull, lackluster or cloudy appearance, it's probably time to empty some or most of the pool water and replace it with fresh water that does not contain high levels of total dissolved solids.
