Your pH reading of 8.0 cannot be trusted when you have high chlorine. So, do not add any muriatic acid at this time.

Is this a freshly filled pool? Is liquid chlorine the only source of chlorine you have used? Just trying to understand why you have no CYA.

Also, you do NOT want a CC reading. So, CC of 0 is perfect!
Hi Watermom,
ok things have changed a bit since I was here last. I filled out the form so all my info is there (wherever that is) but to answer you I tested once and had to put in 33 drops before the water went clear with a taylor k-2006a. concrete, not freshly filled (water has been in for at least 5 yrs since I have owned it. Yes I only use liquid chlorine, but I recently switched from 10% to 12.5%. I believe i have no cya because I put in 8 lbs at the opening of the season and nothing since. I have not added anything as I was pretty sure I would do the wrong thing...I await your instructions...
