I'm glad to be a part of this forum. We just closed on a house with the below pool in signature. I tried to read everything I could prior to closing from this website and forum. I pre-bought the Taylor 2006 test kit and took it to house after we closed. I got the following numbers:
pH 7.2 (Base demand 3 drops)
CYA ~100ppm (black dot obscured a little above 100 but was completely obscured at 100ppm)
The previous owner used a pool company. There were about 2 almost dissolved trichlor tablets in each of the 3 skimmer baskets. Based on all the knowledge here, it seems that is why the pH is low and CYA is so high. Also, the FC should be a lot higher based on CYA.
Due to heavy rain over the last few days the pool was at the top of the skimmer boxes yesterday. The pool water was definitely a little bit more of a greenish hue compared to last time at the property during home inspection.
My questions are:
1. Should I first work on the CYA by partially draining pool in steps to get it down to the 50ppm level before trying to adjust anything first?
2. Do I keep chlorinating based on the FC/CYA chart?
3. I know draining pool will also decrease CH level even lower but should I just worry about that replacement once I have CYA level down?
4. After this, owning a pool will be well worth it right?!
Again, I definitely appreciate everyone's time and recommendations with this matter. I look forward to hearing from you and hopefully will be able to contribute my own experiences to help out in the future.
