Can someone educate me if I need to take any action if my total chlorine reading is 10 and my free is 5. I’m using aqua check spa strips and the aqua check phone app tells me to super chlorinate or shock my tube. I have 450 gallon tub and usually add about a tablespoon of spa 56 when the chlorine gets low and 2 oz of MPs a week. I am to keep things balanced but do not know if my chlorine routine is right.
Thanks for any input
