Filtering Tap Water


Recommended Posts

I'm getting my first hot tub next week and need help preparing. I'm getting the Hot Springs Grandee with Ozone (no Salt). Do I need to do anything with my tap water when filling the tub each time? I do not have soft water at the house, and I'm not sure of the water quality in San Diego. The dealer has both the Clean Screen Pre Filter, and the Vanishing Act Calcium remover, but didn't really seem to push one vs the other. Any recommendations of whether I need either of these or something else? I will be having young kids in the tub, so water quality is something I want to keep clean so it doesn't irritate them. Plus I've heard that you can make the water quality such that you don't even need to shower after you are done. Thanks

San Diego tap water is fine, except for pH being high. I use an inexpensive filter on the end of the hose when I fill, but that probably isn't really necessary. On my last fill, before doing anything, I measured pH >8, FC 0.6, CC 1.0, TA 100, and CH 100. You definitely don't need the calcium remover - I usually add calcium to increase CH to around 150. Knock the pH and TA down with dry acid, add your sanitizer of choice, and you're good to go.
