Well we have finally conquered the problem of our pool not holding chlorine and the water looks great. We are now in the process of lowering the TA which was 250 and is now down to 225. We are using muratic acid and then aerating to get ph back up. Seems like this might be a long process! I am now checking the FC daily. How much ppm is normal to lose in a day? The pool temperature is 51 degrees. Do most people find themselves adding chlorine on a daily basis? Just trying to get a general idea how much bleach I will be adding on a weekly basis.
