Always able to keep pool clear till now, gettin crazy. About a week ago pool started to get a little algae, brushed pool was clear, started gettin cloudy thought it was dead algae...brought fc up to 21 as per calc.. dropped down to 18 overnight brought back up to 21 dropped to 19 overnight, slowly got worse. Can just make out main drain thru the hazy water. Yesterday evening went by cya chart and raised to fc to 28, was 28 as of this morning...gettin buggy... I use cal-hypo 65% as shock....pool is in direct sun all day...numbers are as follows:
Just thinkin maybe filter problems????
Thank u in advance
