Chlorine=bleach?
alk increaser=baking soda?


I'm wondering if there is something for calcium hardness?

Also I've seen the bleach calculator is there one for the baking soda/alkalinity?

I've been using bleach for the last year and have been so happy saving all that money, but I'm still getting killed using the pool stores alkalinity increaser and calcium hardness crap. Any help would be appreciated thx
