So lately if I look at the surface of the water from a certain angle I can see a bunch of particles floating around. At night, if I look directly in front of the pool light, I can see a bunch of particles floating around. I just recently switched to the BBB method (thank god), and I'm wondering if that could have something to do with it. Or possibly the timing of my switch happens to coincide with a bunch of stuff falling out of trees and into my pool? When I used to take my water to the pool store for testing they would always talk about sulfates or total dissolved solids, any chance it's one of those? Also, I was thinking it might be time to change out the sand in the filter, since I don't know how old the stuff is that's in there. I've posted test results below just in case. Thanks
