I have an AG 12,500 gal pool and have used Baquacil for 14 months. I have had no problems other than a water line etched into liner and an odor to the water this summer. I was told that the sand probably needed to be changed to rid the odor. However, after reading these situations and due to the $$$, I plan to convert this spring upon opening the pool. I live in Texas where we have been scorching with over 35 days of 100+ degree heat. I am unsure what to add to pool upon closing at end of Oct. in order to switch to chlorine in the Spring. I just read about a product called Flip-Out which rids the Baquacil while keeping the water clear and safe to swim in at the same time. Do you know anything about this product? Any info will be appreciated.
