Hello. New member. Just got my test kit and started my slam 4 hours ago
When I started I had readings of
CYA 33 or so
Added chlorine liquid and tested.
Just waited a few hours and retested and added more
Added enough to go up to 18FC based on new CYA
I have some questions
Should the CYA have gone up? Very possible that it's me being new at CYA tests because it's hard to see exactly when the dot disappears.
Also should I be aiming on the high side of the shock numbers or try to hit it exactly? It's decreasing over time so I made most of my calculations with some margin of error.
Should I be testing anything else during SLAM? I add DE 1/2 cup to my sand filter and I backwash at about 10-12 psi increase. Any other tips welcomed.
