With every booklet or program I read or use they all have different levels for the chemicals you test for. IE CH, CYA. What are the levels y'all would recommend for a HT? I'm confused.
Thanks

Yep, I've checked out pool calc. It has different values also.JamesW said:
Thanks, I assumed "troublefreepool" meant "pool" and not HotTub.RobbieH said:If you decide to do borates (they are OPTIONAL), then 40-50 is your target. Read about borates in pool school before you go down that path though.
For Pool Calc, select the TroubleFreePool targets.
The pool calculator has an option for hot tubs. Choose "Traditional Spa".knutohotub said:Thanks, I assumed "troublefreepool" meant "pool" and not HotTub.
Thanks, I made the adjustments in Pool Calc and Simple pool apps.chem geek said:I should note that the link to using chlorine in a spa refers to having an 80 ppm TA level, but usually that is too high and a lower TA level is better for greater pH stability, especially when there is more aeration. A TA of 50 ppm along with using 50 ppm Borates would be a better recommendation (and we should really change that post).
