Pool test results from this morning:
Free Chlorine: 28
pH: 7.0
Total Alkalinity: 80
Calcium Hardness: 430
CYA: 200
Water Temp: 85°
(Taylor K-2006 test kit)
Pool specs:
Orlando, Florida
10,000 gal in-ground
Plaster
Chlorine
Variable Speed Pump with pressure gauge
My pool calculator reports the following:
Free Chlorine is a bit high
pH is a bit low
Alkalinity and Hardness OK
CYA is off the chart high
My research suggests I need to drain/replace water from the pool to lower the excessively high CYA. After that is done, re-test, add appropriate chems, re-test after water has exchanged one time, repeat.
Are my conclusions correct? What are my next steps? What order do I do these things?
