Have you ever taken a look at your pool and said to yourself, "Gee, the water doesn't look right." A pool should have crystal-clear and inviting waters, not murky and sickly looking. If the pool water doesn't look right, then you might have algae growth and this can be a bit of a concern. Not only does algae growth make your pool look unappealing, but it can be dangerous as well, as algae is very slippery and can cause accidents.
On top of that, algae has been known to cause allergic reactions in some people, as well as damage your pool filters and other fittings if left unchecked. So at the first sign of algae growth, take some time to shock your pool and keep your pool waters crystal clear.
