What is Algaecide?

As a savvy pool owner, you have to find ways to control the levels of such products. Plus, you have to find ways to conduct DIY checks, especially if you don’t want to invest in a pool service.

Side Effects and Signs of Using too Much Algaecide in the Pool

There are various tell tale signs that you have used excessive algaecide in your pool. Below is a quick rundown of things to expect:


The presence of excessive algaecide in the pool can cause it to become foamy. Usually, this occurs in the form of small bubbles that occur as the water moves through a return jet. The water then travels back into the pool.

However, never confuse the presence of these bubbles and foam with other issues that might occur in your pool. A good example would be the presence of air in your pool lines. Any air pockets in the filter system might produce bubbles, which might get to the surface of the pool. The bubbles and foam that occur due to excessive algaecide will be significantly smaller in size.

Skin Irritations

Skin irritations are also a common side effect of using excessive algaecide in your pools. Any user of a pool that excessive algaecide will come across various issues. These include irritations in sections such as the eye and the skin.

Furthermore, factors such as an imbalance in the water chemistry can also cause irritations in the eye. A good example would be when you use excessive chlorine or when the pool has compromised alkalinity levels.

The uncertainty associated with such irritations makes it crucial to determine when you use excessive algaecide in the water. So, you may need the right tools to help check out the water quality.
