I did not routinely dose algecide last season. But we only had from early Sept to Late October before closing. PB left 2 full bottles of Algecide at opening and I can't decide if I need to use this routinely. They did put a full bottle in at opening. It is Pool Season Algae Control 60. I run my SWG, FC runs about 8, CYA is about 90. Is there any reason I should routinely add this? I want to keep my additives as simple as possible and not add anything that is not necessary.
