I'm pretty sure I'm OK but it's still a little foreign to not shock my pool. I've not "shocked" in almost 2 months now since starting getting the mess caused by poor advice from our pool store sorted out using the BBB method. I'm talking about a non-chlorine type of shock. SWG is set at 20% and keeps the FC between 3.5 and 4.0 consistently. CC stays at zero so is there any real reason to shock or otherwise oxidize the water? Water looks great. Thanks in advance!
