What is Algaecide?
Algaecide can appear to be a miracle solution to algae growing inside your pool. It’s a type of chemical that prevents the growth of algae. It can be used in various bodies of water like swimming pools. Algae is a plant that prefers to grow in warm and nutrient-rich water. It’s . Algaecide works by breaking down the cell walls of the algae, which prevents them from growing and reproducing.
Algaecide solutions are either made from copper or polyquat. The widely held preference of pool professionals, including ourselves, is to use polyquat algaecide over copper algaecide. The reason is copper-based algaecide has a higher likelihood of staining your pool.
Removing Algae: Algaecide vs. Pool Shock
You may be shocked (pun-intended) to hear this, but algaecide isn’t the best way to kill algae in your pool. Instead, pool shock is often the proper chemical to add. If you’re using your pool in the middle of the summer, use pool shock. If you’re beginning or nearing the end of your pool season, consider algaecide. Pool shock also has many other benefits. It’s important to know the best time to shock your pool and how often you should shock your pool.
You can absolutely use algaecide to prevent algae growth during the summer. However, be very careful, especially with copper algaecide. Using pool shock instead is far less risky. If you’re sure you want to use algaecide, apply small doses and re-evaluate.
When Should You Use Algaecide?
Despite pool shock being our preferred way to kill algae, there are some times where it’s useful to add algaecide. Algaecide is especially great for closing your pool. This will help ensure that your pool doesn’t experience algae growth if the pool water becomes warm.

Why Does Algae Grow In Pools And How To Prevent It
Algae is very common in pool settings. As we mentioned earlier, pool algae typically presents itself in late June and early July. Why does this happen? Algae thrives in warm water and this is usually the point in which pool water becomes a higher temperature. This is coupled by the fact that usually by late June, all of your attention to chemical balancing during the opening starts to drift away.
Knowing when algae begins to form and grow is half the battle. You can start to see the signs and act accordingly. By shocking your pool regularly, you can prevent algae from starting.
