...water beetle!! We've had rain the last 3 days and the sun has come to visit today...imagine my surprise to find this thing floating dead (thank goodness). The tile on the seating ledge is 3x3 to give you an idea of the size of this thing. I included it next to a quarter. Please tell me it's just a fluke and there are no more of these things hiding out somewhere in my pool; not like I could miss them! My water was a close to perfect as it has ever been about a week or so again but last test numbers on 7-9-15 @ 7pm...
