Ok, I've been given a hot tub cal spa 1997, from my inlaws and I have read many postings about starting up but I am looking for the dummies version. What is TA? Is there a step one, type version? I will be filling with water softened well water ( my pool had no issues but some iron I filtered out - never had to adjust ph (perfect) and only added chlorine ever) but heated water and spa care and set up is new world. Walmart sells products- bromine or chlorine? I'm thinking bromine is less work? I am starting from scratch. Link to idiot level instructions??
