So I have been devouring this site trying to get rid of my pollen/ mustard algae problem. I was convinced it was algae at first so i shocked the pool and kept it at 45 FC for 2 days while brushing alot. CYA of 60. Only loss 1 fc overnight. But I still had the problem so I now am convinced it is pollen. But just to be on the safe side before I add a skimmer sock and DE to my sand filter I sucked up some of the substance in a syringe and added some bleach to it. Before the bleach it would settle on bottom of syringe only as a very fine slime and would disappear when shock to a hardly visible smoke. After the bleach I had very noticable clumps of material of bottom and when shook it doesnt smoke anymore, it just floats up and settles back down. And the volume of material seemed to triple. Now I am very confused because that seems like algae to me. Its probably 1 part of bleach to 5 parts pool water ratio wise.
Thanks in advance.
