I’m a little confused when it comes to TA in my hot tub. My local pool/spa store tells me the ideal range is 120-150ppm. My test kit says 80-120ppm. And many threads I’m reading on here says 50-70ppm. So which one is it?! I’ve been keeping it at about 120-130 but am battling constantly high PH readings so I was thinking of lowering my TA. But what is safe? And why are there so many different recommendations out there? Thanks.

Hello. I am new to this forum and also a fairly new hot tub owner. I am having trouble with my chlorine levels, specifically getting rid of combined chlorine. For the first couple months I was just using non-chlorine shock and a chlorine floating thing. After doing more research I realized I should also be using chlorine shock. So last night my FC was at 5.0 and by CC was at 1.2. I threw in 2 Tbs of Dichlor (that’s how much the instructions said to use to get my FC to 12) and left the jets on and lid off for an hour. 12 hours later I tested it and my FC is at 11.2 and CC is 2.4. Why has my CC doubled? I thought the shock was supposed to kill it?
