Long story short.
My CYA level was at like 200.
CH was at 750.
This was before I fired the pool guy and started TFP method.
I replaced about 40% of water after which the pool looked very clear.
Today I saw that it was not as clear as it was just after replacing water.
My current CYA level is 90-100
CH - 625
It may be a false observation since I am new to this. I have attached a pic. Its 7pm PST so its not that bright outside.
