Hi there tfp well I finally recieved my new kit and did a sample on my 20,000 gallon swamp and plugged in the numbers into the pool calculator chart and it said to replace 64% of the water with new water to bring down cya level to 40. I just wanted to run this by the forum to get some opinions before I proceed in draining 64% of pool water

Fc= 0
Ph=8.2
Ta= 110-120
Ch= 450-460
