I bought these tablets a while back and use them mostly in summer with tap water: https://www.amazon.com/gp/product/B000FF76KM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
paid under $10 for 25pcs tube, they work very well. Of course they are out of stock now. One can make their own winter fluid as well, there are recipes that can be found online.
