Might help if you post a picture. You can either use Flicker, Picassa, etc. or you can email them to [email protected] and reference the url of this thread.

Welcome to the Pool Forum!

I'm with you .............. I wouldn't want to get in a pool filled with black leach like bugs!!

(I know you are shocked to hear this, right Ben? )

Sounds like spring tails.

Spring tails originate outside your pool -- you have to deal with them there, before they enter the pool. Here's a fairly authoritative guide: http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn74136.html

And general info from Wikipedia:

And, a thread from last year:

And, some pictures from Google Image Search (safe search ON, but still GROSS close ups of *bugs*)
