Then the pool looked like this.
Not pretty. Approximately 3 days and a gazillion dollars in chemicals later, it looked like this.
Only slightly better. Finally we called in a second pro to help us out, and we ended up draining at least 1/3 of it. Finally now, it looks like this.
As much of a PITA as it was, we really do enjoy it... now if we could just get one more good heat wave before it's time to close up...
