I recently switched from pucks to bleach. All is going well. However, I noticed everyday a significant drop in FC level. CYA around 40-50 so I shoot for an FC level of 5-6 ppm. I add bleach in the evening to get this level and when I get home the next afternoon, I'm usually down around 1-2 ppm FC. I add bleach and bring it back up to around 5-6 ppm and so on and so forth each day. The pool is in full sun and it's been in the upper 90's recently in PA. Should I be concerned with this significant drop every day? Is there a way to maintain the level using bleach? This is an advantage to the in line's with the pucks, that they maintain a relatively consistent CL level (I understand the disadvantage of the CYA). I guess the real concern is continually dropping below my minimum FC level and the potential for an algae outbreak. Fishing for any thoughts on this.
