What are these? Had my dolphin for 2 years - this is the first year I have seen this...
I am in the middle of a SLAM and have had FC over basically 25 Sunday. I last ran my robot on the 19th (last friday) but have been brushing daily. I actually noticed some in my spa after the robot completed.
Im in the LA area - no rain recently though I do have a ton of overhanging eucalyptus trees.

They are tiny, smaller than the speed stir magnet

here are some at the bottom of my hot tub
