We bought this house about a month ago, haven't switched to BBB yet, just using 3" pucks (two in each skimmer and they last 5-7 days approx.). Water has been crystal clear.. until today. Water is extremely cloudy which I am guessing is high CYA. Only recent change is I tool the four filter cartridges out and cleaned them with a hose late last week. What that cause this? Any idea how to remedy other than partial drain?
