I used baquacil in my pool this year and want to switch to chlorine. My local retailer suggested that I add 4 bottles of chlorine before closing my pool for the winter, leaving me completely unprepared for the chemical reaction which ensued. Now, I seem to have started a massive conversion that I'm feeling very intimidated by. I've read many threads here and it seems to only be adding to my intimidation factor (since I'm totally unfamiliar with all the terms being used... ppm? FC?). My main question is this: wouldn't it be easier to empty the pool, clean the liner, clean the filter and then refill the pool and start from scratch? What would the main drawbacks to this be? Thanks in advance for your help!
