Hello! I'm Robert and this is my swimming pool blog. I love to go for a morning swim, so when my wife and I moved into a large house with an outdoor pool, I was really happy. However, after a summer of fun, I was dismayed to discovered that the water in the pool had turned a funny colour. I had no idea what was going on so I called in a pool contractor. The contractor explained that the pH levels in my pool were all wrong. He added some chemicals and before I knew it, the water was clear again.
