Pool is finished! We used Ocean Blue and absolutely love it. We didn't add anything to it. In the middle of the day, when sun is shining directly on it (first picture), it's lighter than I was expecting. However, the different shades of blue throughout the day and evening are stunning. Today is cloudy, so it's a darker color pool right now (rest of the pictures),... just how I like it. I was told that it's harder to see in a dark colored pool. That hasn't been an issue for us. One of the pictures attached is looking through 8.5 feet of water, and you can see the grey drains and black vacuum just fine. Another picture shows a seating ledge in the deep end, so you can see the color of the Pebble Sheen on the ledge, versus 8.5' of water. Pool was filled with water 2 weeks ago.
