Ideal-chlorine-level-for-pool, if the ph level is too high, even having the right level of chlorine won't be enough to make sure the water is safe to swim in. chlorine loses its effectiveness in acidic water. shoot for a ph that is the same as human tears--around 7.2 but up to 7.6.. Ideal levels of free chlorine, combined chlorine, and total chlorine the association of pool and spa professionals recommends free chlorine levels be kept between 2.0 and 4.0 ppm. the center for disease control recommends free chlorine stay above 1 ppm in pools and 3 ppm in hot tubs., welcome back students! today in pool chemistry 101, we cover some common chlorine concerns for pool owners.. the topic is the best chlorine levels for swimming pools; let’s start with the general, and move towards the specific..

A high ph gives: – poorer chlorine disinfection – skin irritation – lime precipitation – cloudiness . a low ph gives: – aggressive water, which damages the mechanical components of the pool, that can vary pool to pool. with that said, pools that have users in for long periods of time such as high schools with swim teams should run about 1.5 ppm.. Chemical. ideal level. to raise. to lower. chlorine. 2.0. shock the pool. turn chlorinator down. ph. 7.4 summer. 7.8 winter. add soda ash *add muriatic acid (diluted ..., ideal chemical ranges for your swimming pool. people often ask me, “what’s the big deal with testing and balancing pool water?does it really matter?” i think sometimes people expect me to look around to see that there’s no one within earshot, and slyly whisper, “nah, it doesn’t matter.none of these chemicals really do anything important..

Hi matt, a few persons well versed in pool chemistry, ben powell and chem geek, to name a few, make the suggestions and offer proof that – as cya levels rise, one should also maintain a higher level of free chlorine, for daily sanitation and a higher target range for superchlorination., for most accurate testing results, pool and hot tub/spa owners should use a dpd † test kit to measure free chlorine and ph. of note, if the free chlorine concentration of the water sampled from the pool or hot tub/spa is more than 10 ppm, the test might partially or totally bleach out, resulting in a false low or 0 ppm free chlorine result..

The stabilizing effect of cyanuric acid does not increase as the levels increase. instead the chlorine becomes ʺlocked inʺ at levels over 100 ppm and may not be as effective in killing bacteria and algae. in other words, more is not better.
