A week or two ago, I went through the SLAM process to kill algae (green). All has appeared to be fine and we have been using the pool daily.
This morning my readings are:
FC - 0
Cl - 0
TA - 70
CH - 250
CYA - 80
Ph - 8.2 (as best as I can read)
I have added Chlorine in the form of liquid bleach as recommended by pool math.
I am not sure my SWG is working properly....how do I tell?
