Hot tub is 385 gallon, around 94 degrees (if that matters). Fresh fill on Wednesday readings are the readings for our tap water.
Fresh fill on Wednesday:
- FC:1 pH:7.5 CC: N/A TA: 30 CH: 40 (This is before adding anything)
Added 1oz dichlor and 1.5 oz baking soda the next day:
- FC: 8-10 pH: 8.0 CC: N/a TA: 65 CH: 45.
Added 0.4 oz dry acid to bring pH down. Got it stable at 7.6, and then poured in a bottle of pH Lock.
Thursday night: added 4 oz of Calcium Chloride (Clorox Brand Pool & Spa Calcium Hardness Increaser) - and that's where the weirdness started.
The water became cloudy and the TA shot up to around 180 from 65. pH did not really change at that time, but then was relatively low this morning at 7.2. TA fell to around 110 overnight. There was also some fine white sediment that settled in the tub.
Should I just let it level out, or have I just screwed my water up? It's not the end of the world if I have to drain and refill, but I'm new to this and trying to follow the pool math (on Traditional Spa setting) to figure out the right way to go about this, and this one is baffling me.
Any advice?
