We had a 27" agp pool installed this past weekend and want to go the BBB route. However, we have a bunch of 1" and 3" chlorine tablets leftover from last year's intex pool. Are they of any use anymore or should we get rid of them? If they aren't of use in our new pool, how/where do we dispose of them? After adding a gallon of bleach last night, the FC level was at 5 and we have CYA of 0. Thanks in advance!
