We are new pool owners. We have a 30,000 gunite pool which we opened a month ago after buying our house. The water was a dark green and we managed to bring it back to a clear blue with the chemistry perfectly balanced. We had some pretty bad stains and on Tuesday, I used ascorbic acid followed by metal free to get rid of them as suggested by my local pool company. A day later most of the stains were gone and the water still looked great. However, since yesterday the water is cloudy and you can't see the bottom of the pool any more. I went to my local store and here are the reading.
The guy at the local pool store told me to shock it to clear the water. I don't want to do this, since I read that I should try to slowly bring the chlorine up by adding bleach. Any suggestions, not sure what to do at this point.
