I am new to the world of chlorine pools. I was drawn into the Baquacil products when I purchased my pool 8 years ago. I had decent results, however I spent $600+ last year in chemicals. My pool is above-ground, vinyl liner, 24' - round. I am using 3" chlorine tabs I purchased from the pool store (1 every 2-3 days), 1 bag of shock/week, and baking soda (as needed, when alkalinity is low). My water is sparkling clear and comfortable. However, after reading all the posts ... can I merely use bleach on a weekly basis and nothing else? I have looked over the articles on the section "pool school" but all the chemicals and names are a bit overwhelming.
