Q: I have recently had a medium-sized pool installed in my backyard, and my family and I have used it a lot already to cool off from the summer heat. However, the water is starting to look a little green, with a build-up of algae forming on the steps and in the corners. Why has this happened, and how should I tackle it?
A: Green algae spoils the look of a backyard pool, not to mention, makes it less inviting to swim in. Plus, it can pose health risks: it encourages the growth of harmful bacteria which feed on it, it reduces visibility, and it can turn steps into a slip hazard. Over time, it can also stain the surfaces of your pool and even clog and damage the plumbing.
