I inspect my pool every day and found this at the bottom. Just vacuumed 2 days ago and did not notice it, but can't say for sure if it was not there or not. Pool is screened in, so this had to be brought in, not flung by a lawnmower, droped by a bird, etc.
I've checked all the pool toys the kids play with, the manual vacuum, brush, the patio furniture, and the pump / filter system. Nothing else enters the pool area. Looks like some kind of clip.
Its about 1/2" square. Can anyone ID this? TIA.[attachment=0:1w06y3hq]100_4017.jpg[/attachment:1w06y3hq]
