Identifying the growth in your pond is the first step to controlling it. Not all growth is necessarily bad. Some types of algae, such as chara, act as filters that keep your pond water clear and clean. In order to control and kill unwanted algae, ponds should be treated with an algaecide several times a season. Our products give you a safe, cost-effective way to maintain algae growth before it takes over your pond. For more information view our Frequently Asked Questions.
