When I went to clean my skimmer box I noticed a large number of small
wriggly black larvae attached to the pump intake. It is a slotted piece of
PVC pipe. I am using a Sequence 5800, a 5800 GPH pump. I see them both at
the intake area and attached to the strainer in the priming pot. Some hold!
Do you think these are leech larvae? Any other ideas?

Thanks,
Tim

Probably black flies. Kill them before they turn or you'll be sorry.
