1,284 litre hot tub. Got an 11ppm free chlorine reading (fine for a spa) and a total chlorine reading of 25. The app recommended putting a LOT of calcium hypochlorite in. I thought it was odd but figured it must know what it’s doing. My spa is now full of extra strong bleach with readings off the chart and I really hope it hasn’t damaged it. Now having to drain it, and refill it with cold water which is going to cost me.
Did I do something wrong or does the app have a bug?
Formula set to Chlorine (calc-hypo), custom chlorine max level of 11, everything else default.
