I am wondering if I have just fine dirt/silt that settles to the bottom of the pool or is it algae/dead algae?
Its brown in color and it settles at the bottom of the pool when the pool is still. I recently vacuumed it all out (not to waste) and then about a few days later more of it appeared on the bottom. I'm afraid if I vacuumed straight to waste I'd end up draining a whole lot of my pool!!
I've always thought it was fine dirt - coming from the kids running and jumping in, debris blowing in, and the fact I use solar covers and that when I take them off stuff rolls off of them into the pool. But now I'm not sure since it returned within a few days.
The water has been clear and my test results have all been good through the past few months and not losing chlorine. My latest results are:
CYA: 50 ( I recently added more CYA to get back up to 70)
Just not sure if others have had this issue or any input? Sorry I don't have any pictures. Thanks.
