I have a gunite/plaster 22,500 gallon salt water pool. I recently was hit with a big issue: Chlorine demand and 0 CYA.
Here is my test kit (Taylor) Baseline Post bucket test before Tx:
Salt (reading from SWG): 3000
I treated immediately w/ Bleach and Stabilizer. FC remained stable for 36hr at 2-3.
Here are my current readings:
CYA: 30 (rising slowly over last 36 hr)
Salt: 3000 (questioning if SWG is functioning)
Issue: am I on the right track? Pool is still green and cloudy but much clearer than when I started.
We backwashed and I used the Pool Math (love it!) to add 4 more jugs of 6% chlorine and 4lb stabilizer. I am adding one bag of salt due to base reading of 2600. Do I treat the CH? Pool math indicates about 16 pounds based on formulas.
I feel like we are gaining and I do not want to lose momentum.
