Root Killer in Swimming Pool: Use of Algaecides to Kill Algae

Root Killer in Swimming Pool

You wake up one day, and your swimming pool has turned to cloudy and green from crystal clear. Maybe you allowed your pool chemistry to unbalance while on vacation or someone didn’t wash their swimsuit. 

It happens to most of us, do not fret out. Whatever the situation, you need to remove algae or roots from your pool. 

Very easy, you might assume. I will buy some root killers in the form of algaecides. But before you do that you need to answer the following question: are algaecides the best products to remove algae from my pool? 

And here we will try to give you the answer to that question to help you kill roots from your facility.

How Root Killer (Algaecides) Works

Many root killers are copper-based – made of copper chelates or copper sulfate, which are chemical elements with metal as the primary atom. A few safe algaecides use sodium carbonate peroxyhydrate or herbicide endothall and are often registered. 

These products all interfere with the algae cellular processes, although studies have not explained how that occurs. Maybe they disrupt energy intake or roots cell division or perhaps inhibit the synthesis of fresh cell proteins, which are critical for algae survival.

The bottom line, we all know that root killer work – to some level – but the reason for their effectiveness is still not known. It is vital to note that if your pool is located in an area with high metal content and it has water, you might suffer from oxidation which often stains pools.

Adding root killers made of copper can enhance this process. If you must add algaecide, go for a copper-free model to help maintain your pool floor and walls. 

Common Algae to Remove

The most common forms of pool algae or root that you might come across are:

  • Black algae – It is the most frequent kind of algae to remove from a swimming pool.
  • Green algae – The most common type of algae, especially if you leave your swimsuits unwashed.
  • Pink slime or pink algae – It is a bacterium, but often treated as an alga due to its slimy looks.
  • Mustard or yellow algae – Hard to come across but it is challenging to get rid of and quite uninviting to the swimmer. 

Shock the Roots – The Pool

If your swimming pool is infested by roots, shocking the water should be your priority. You should also scrub the surfaces as hard as you can. 

Root killers can speed up the process, but they can result in other problems. Thus, unless there are chlorine-resistant roots like black and mustard algae, you shouldn’t consider using algaecides. 

How Much Root Killer to Use?

One ppm of copper in water is safe, and 0.5 ppm is sufficient to kill all algae in your swimming pool. Copper sulfate contains about 20-25% copper; thus, a 50,000L pool requires 100-120 grams of this product.

There are test kits that can help you to test the amount of copper in your facility. 

In Conclusion

You should avoid root killers unless there are algae that cannot be removed by chlorine. If that the case, use the right dose to ensure that you don’t destroy your pool.
