Guess we had a lot of wind at some point early this morning.....I could see some dark areas on the bottom of the pool from the house but it wasn't light enough out yet to really tell what it was. Walked out there and was like OMG, there were small limbs with leaves on the bottom and the entire top was covered with catkins from the oak trees. The entire skimmer was full catkins, not the basket, the whole thing...LOL. Haven't had much in the way of catkins the last 3 days until last night. Got the pool all cleaned up, tested FC and added accordingly.
