    1. Stuck in Low TA / High pH Loop in a 205-Gallon Hot Tub - Losing My Mind
    2. Got a 20 year old Cal Spa for free. $300 to move. About $2000 for dedicated electrical line. $650 for a custom cover. The hot tub itself works really well. Jets run strong, it holds and gets to 104 easily. The prior owner took good care of it and seemed to hardly use it. I took a risk but paid off!
