I recently finished my slam passing OCLT, water looks great, and combined chlorine of zero. My CYA is a 70 so my SLAM level for full chlorine was 28. Currently I am waiting on my chlorine to fall to get an accurate PH and TA reading. Am I correct in saying that those won't be accurate until I get my FC below a 10? Right now I am at a reading of 16 FC. I feel like I have read that somewhere but not sure where on here. Thanks so much!
