I apologize, but I don't have my own test kit. Luckily I don't think my question will really require test results.
I've been using cellulose fiber with my sand filter. I slowly spread the fiber on the water in the skimmer drain. 2-3 cups until I notice any change in the psi. It definitely seems to make my sand filter (which I am not impressed with) catch more ****.
Lately I have noticed a lot of little tiny flaky looking things floating on the pool. It's been pollen season so I thought maybe it was some kind of tree or pollen byproduct. If you touch it, it disperses into much smaller particles, even so small you can't see them. Then I think they float around, bump in to each other and reform the visible particles. I then hypothesized that it was cellulose fiber. I grabbed a tiny speck of it from the bag and dropped it into some water and confirmed the flakes I am seeing are grouped cellulose fiber particles.
Anyone heard of this? Is it coming out of my sand filter? Just some fiber that the wind blew off my cup onto the water? Some of the fiber isn't getting pulled down the drain? How can I get rid of it (nets don't catch it)? Maybe a while using skimmer drains only will clear it up (I've been using my pool vac a lot lately, so not as much skimmer action)?
Thanks for any responses!
