Hmm, when you say sink to the bottom - do you mean when they die, when they are reproducing, or just to hang out?
This is the only piles I see on the bottom.
The problematic ones so far are the ones floating on the surface of the water (still alive). My net at the skimmer is catching them (and other gunk that's good to get out).
