Swimming Pool Glossary: Simazine

Simazine Banned
Simazine is an herbacide and algaecide. Often used to kill black algae, you can no longer buy simazine in North America.

Simazine is very water soluble, and thus works very well at killing algae. However, because it is so water soluble, simazine tends to contaminate your water table, making you sick. In fact, simazine can just as easily get into your water table as it can kill your pool's algae. This is why simazine is now banned.
