I'm a new owner of a 1950'ish ~22,000 "in" ground pool. My family and I don't live there yet because we are about to renovate. We are about 15 minutes away and check on the house about once a week. Several weeks ago it got warm and turned green over the work week. I went to Leslie's, purchased a three step shock and clean products, which worked. Last week, it turned green again. I searched and found this site and read about CYA and chlorine pucks, which I was using and I'm sure the previous owner was using. So, when I tested the CYA levels, using the black dot in the test tube, it was above 100. Using the calculator on this site I drained the pool approx. 60%, which took about two days, filled it back up, and have been keeping the chlorine at shock levels using liquid chlorine or bleach from the grocery store. I'm doing this the best I can with work and not being able to live there, but it is sparkling now. However, I checked and the CYA was at 100. My wife took a sample to Leslie's and they too said it was around 100. Yet, they said 100 is normal around here and I'm fine. I thought I wanted my CYA around 50? I also thought draining the pool 60% would have brought that level down a lot?
Why would the CYA levels still be that high after a drain?
Is a 100 level ok? If yes, how much liquid chlorine should I expect to use a week? Will I be able to test and dump on weekends?
I live in Altadena, CA and we are in a record drought, so I already feel bad about filling the pool. I am thinking of waiting until this winter (rainy season) to drain the pool again.
Thanks,
