I have a question regarding calcium hardness
We use a Water Softener to fill up the hot tub (I know it is not to be done), but what I'm wondering is, if I was to add calcium to my hot tub, it would increase the hardness level, Which in return should null the effect of a water softener? Correct or am I missing something here with that?
Thanks.

correct, you can add for a very cheap cost liquid calcium to the spa, just don't go overboard, I find 75-150ppm for calcium hardness is a good level where it's not too hard and not too soft. Good Luck!

I'm thinking you should have a water line at your house that bypasses the softener.. for watering outside plants etc. Most houses have a provision for this.

My home uses a water softener and the outside hoses come off that same softener. The only thing not using that is the irrigation system which uses ground water (unfiltered and nasty grey water). So I need to get some Calcium up also. Just wondering per this thread, how important is this? Immediate action? Couple weeks ok?

I personally have naturally soft well water and have used it for years with no ill effects...

Two different test strips show me down/around "zero" as far as hardness goes.
I picked up some calcium chloride on Amazon (less expensive "food grade" than "spa grade"). Would you say this page properly takes care of the math? https://www.horizonpoolsupply.com/resources/calculators/raise-calcium-hardness (https://www.horizonpoolsupply.com/resources/calculators/raise-calcium-hardness)

It would work to about 100 grams of the Calcium so that sounds about right. I had to put that amount in as per recommendation from my water testing company that sells the supplies for our tub.
