I am from central Indiana and I just bought a hot tub and the water clouded up after a few days. High alkalinity, hardness and pH - it took me a bit to find my way to lower the alkalinity to around 50, add some borax and I now have stable pH. Turns out the groundwater here is about ~350 ppm for both hardness and alkalinity. I'm glad that is solved and I know my way around for next time I fill.
However, my combined chlorine is stubborn at 0.6ppm. I raised the FC to 15 yesterday, confirmed with my Taylor test kit. Today the FC is at 5 and CC is still at somewhere between 0.5 and 1.0 (I used a 10 ml sample). I suppose I just will raise the FC again and see if the CC budges. I have some Ahhh Some on order, along with borate test strips, and an extra set of filters. How high should I be raising my FC? Do I repeat this procedure until I see some movement?
ph 7.4, FC 5.0, CC ~0.6, CH 200, CYA 30. Ozonator is running.
