I have very fine brown particulates (dead algae, more like dust in size, you can way your hand near it and it becomes invisible it's so fine) that settle on the seams of my vinyl liner. I vacuum weekly going very slowly and methodically, but they come right back the same day. I don't know the size of my sand filter but it's about 4.5 feet high at the multiport valve.
Would adding DE help with this or should I just bite the bullet and vacuum straight to waste? As methodical as I am about vacuuming i'd be wasting a lot of water. Any links on how to add DE to a sand filter would be appreciated as well. I know I've skimmed a couple here. I'm against vacuuming to waste as I do about a 1 hour vacuum job and that would likely have a big impact on my water chemistry.
When I backwash the filter window is practically clear the entire time with some particles floating around it.
Thanks in advance.
