Starting to worry after reading some threads. Water temp yesterday was 79. A few days of warm then that's about it....stayin around in the mid to high 70's during the day and about mid 50's low 60's at night from here on out....think I'll be ok? Skimmer is has the plate on, light is out and plugged up....no way to run the filter unless I "undo" that headache. I had a high chlorine level, ph on the high side of normal and put in one bottle of AlG 60...I guess I'll wait for you smart ones to respond and in the mean time keep me fingee's crossed!
