What ppm should free chlorine be?
between 1.0 and 10.0 parts per million
In ANSI 1, the levels should meet the following standards: free chlorine levels should be between 1.0 and 10.0 parts per million (ppm) with bromine levels between 2.0 and 10.0 ppm. ANSI’s ideal range is 2.0 to 4.0 ppm for swimming pools.
How much chlorine does it take to raise 1 ppm?
(CalHypo is 2 oz/10,000 gal to achieve change of 1 ppm, Chlorine gas is 1.3 oz/10,000 gallons to achieve 1 ppm of change).
Is 8 ppm chlorine safe?
Safe chlorine levels range between 1 and 3 parts per million. At concentrations above 6 ppm, the pool is unsafe.
Can you swim 10 chlorine ppm?
What chlorine level is too high to swim? It depends on who you ask, but the acceptable range is between 1 to 5 ppm, per the Water Quality & Health Council. (So, for example, 10 ppm chlorine is not safe to swim in — that’s too high, so it can be dangerous.)
