 skimmer
alot of cure it nows dont work. well 99% dont work. make sure you use a ro unit {no tap water} just in case, dont know your lvl of experiance. alot of cure it nows have some type of slime coat and will make skimmer's run wet. hence wtaer over flow in skimmer. stress coat does the same thing. turn skimmer off for a few days. just a thought since i dont know brand or exactly what you used |
