Getting Rid of Algae in Your Swimming Pool or Spa

As you know, having your own private swimming pool is a luxury that many people covet.

The benefits of having a pool are numerous — increased health, decreased stress, and added value to your home to name but a few.

However, one of the biggest bugbears for pool owners is uninvited guests, and I’m not talking about that awkward uncle of yours.

The intruders in question are algae.  

One of the most frustrating things about owning a pool is keeping it clean and safe for your family and friends to enjoy.

Having a pool that’s unsafe to use turns your pool into an expensive ornament at best, or a dangerous eyesore at worst.

Why Removing Algae is Important?

While algae in itself isn’t necessarily life-threatening, the fact algae is able to grow in your pool means that the chlorine levels are not only too low to kill the algae, but also are too low to kill off the other dangerous pathogens such as bacteria, viruses, and amoebae that could also be lurking in your pool.

In addition, left untreated, the water could turn so murky that a struggling bather might not be seen.

Green algae indicates there is poor water circulation or the sanitizer levels in the pool are low. It’s easy to combat by increasing chlorine levels or by adding an algaecide. It’s actually very easy to avoid green algae by maintaining correct chemical levels in your pool.  

Black algae grows in the pits in the plaster on the sides and bottom of your pool and thrives when the water isn’t circulating properly. It’s one of the most tenacious algaes to get rid of, but with careful and repeated scrubbing, it can be removed as long as the pool chemistry is correct.  

Mustard algae is the most irritating of the three algaes to deal with.

First, it can be problematic to correctly identify as it could pass as pollen or sand particles.

Second, it can appear in chemically balanced pools.

Third, it’s easily transmitted from rain, or previously contaminated pool equipment.

Treating it can be done with an algaecide specially formulated to eradicate mustard algae.
