Not really sure what this is...

You probably got your chlorine levels high enough and caught it at the beginning stages, excellent to hear it's cleared up, at least you'll know what to do immediately the next time you see it - this particular one can get nasty.

I hope you are wrong and it wasn't algae but...I had shocked it and ran the barracuda for about two days straight so maybe that IS what did it...in any case, I am just happy the solution was so simple this time around! Thanks for your info in case I ever need it again! (Crossing fingers I DON'T )
