Too much of a fantastic thing, when it comes to your swimming pool’s chlorine levels, is simply dangerous. While most pool owners worry about keeping enough chlorine in their pool to reduce disease and bacteria from occurring, occasionally the opposite occurs: chlorine levels rise too high to float safely. Perhaps you simply added too much, or an imbalance in your water chemistry, such as particularly high cyanuric acid levels, enables chlorine to build. Permit your levels to reduce naturally before permitting swimmers, or reduce the chlorine levels through treatment or dilution.
Examine your pool water to determine the exact chlorine concentration. Dip a test strip 12 to 18 inches below the water surface, eliminate and wait several minutes as directed by the test strip instructions. Alternatively, use an evaluation kit, adding a reagent into a small water sample in accordance with the kit instructions. Compare the colour of the hat or strip into the controller color given by the product manufacturer to ascertain chlorine levels. Safe chlorine levels range between 1 and 3 parts per million. At concentrations above 6 ppm, the swimming is dangerous.
Eliminate current chlorination, turning automatic chlorine feeders off or removing a chlorine float from the pool. Do not introduce any additional chlorine until a chlorine test indicates that the levels are appropriate again.
Uncover the pool, if covered, during the day. Since the sun’s ultraviolet rays hit the water, chlorine slowly dissipates. Monitor the pool water, testing for chlorine every day, and restart chlorination just once the levels are approximately 2 ppm. This is the normal, evaporation method.
Turn your filtration system setting to”Backwash,” open a drain plug or simply use a pool vacuum to eliminate a portion of the pool water. The precise quantity to drain will vary based upon your chlorine levels and pool size. Run fresh water to the pool to dilute the existing chlorine and then retest the levels. Repeat until the chlorine levels return to perfect. This is a dilution strategy.
Pour a measured dose of sodium thiosulfate, a chlorine neutralizer, into the pool skimmer or broadcast directly into the deep end. Consult the product specifications to determine the precise amount needed. Typically 2 ounces will reduce the contamination level by 1 ppm in 10,000 gallons of water. Add the neutralizer slowly, testing after adding roughly half, to make certain you do not add too much; it is extremely hard to increase the chlorine levels satisfactorily you if unnaturally neutralize the chlorine.
Turn on the pool pump and filter, if it isn’t already running, and let properly balanced water to circulate for many hours. Examine the chlorine levels before turning off the pumps or covering the pool to ensure the levels remain adequate.
