Hello,
I have 350 gal, stand alone, covered hot tub and live in San Diego. I have just refilled my hot tub with hose water for the winter.
1. Do I need to put metal remover in it?
2. I am currently doing the PH/TA Aeration process to get me TA to around 60 or 70. When is the best time to add the Borax in order to stabilize the PH?
3. What is a good Calcium level in a hot tub? Mine is at 150 currently.

Thank you guys for all your spot on advice!

Not unless you're having metal issues. If so check here first before adding anything.

Once you get the TA down.

Acrylic hot tubs have no minimum CH requirement. Yours is just fine.
