Free Chlorine Low Total Chlorine Normal. I have a 18 foot round pool and i seem to be having chlorine demand i test the water and i get no chlorine reading i took a sample to a local pool store and they said my total chlorine was at around a 3 and my free was at 0 my ph and alkalinity reading are fine my cya is a little high at 80 but it read that last year and didn’t have this problem i added powder chlorine and then. Free chlorine is the most important type of chlorine to monitor because it is responsible for actively sanitizing your pool.
You can get a “chlorine remover” chemical if it is urgent. If your pool water is much higher than that and you are spending a lot of time exposed to it, then it could have some effect on you even at these lower concentrations. Total chlorine is free chorine + combined chlorine.
Total chlorine is the amount of chlorine, used or not, in your water.
Chlorine that is chemically combined, such as chloramine compounds. If the levels are off, you should add the chemicals you need to get the free chlorine in the right range. My chlorine reading using the original kit shows ideal to high and the ph ideal. You must reach breakpoint chlorination, which is the addition of chlorine to your pool equivalent to the combined chlorine level times 10.example:total chlorine = 1.5ppmfree chlorine = 1.0ppmso.
