I had a bad outbreak of algae about a week ago. I think it was due to adding too much cya. Anyway.. I have shocked it pretty good with plain bleach to the point it's just cloudy now. The CL level is still too high for me to get a really good measurement right now since I don't have a decent test kit. Using the dilution method it appears to be about 25ppm-30ppm (however accurate that can be).

Today trying to get rid of some of the cya, and lower the CL level a bit I noticed there are critters living in the pool now! about 5-6" underwater they seem to have little wings and more or less hover in place. What the heck are these and what am I doing here?

hep!

thanks.
