I'm not surprised. Here's what my pool service left us with after we'd been paying them to come twice per week.She's the person we rely on and trust most at this place too. I am really surprised.
And a month after that, the water got cloudy. That's when I fired them and took things into my own hands. Trouble free ever since.
Lesson learned: relying on a pool service is hazardous to your water quality and your wallet.
