Pool Owners have little / no control when it comes to the environmental factors that influence algae growth. Environmental factors can be airborne debris, phosphates, sunlight, temperature and nitrates. The best ways to prevent algae are to ensure that you are filtering properly, maintaining a sufficient amount of chlorine, brush the pool regularly and use a preventative algaecide.
Some algaecides are great for killing algae and others are great for preventing algae growth. Some algaecides are great for both killing and preventing, such as a Copper-Based Algaecide (Algae Break 90) and Ammonium based algaecide (our “Red” algaecide). Then there are also “Poly” Algaecides. All of our Algaecides come in two different concentrations.
How Do Algaecides Work?
Let me tell you that algaecide is not a magic wand that will get you rid of algae in the pool instantly. But it’s for sure that Algaecide is a very effective way of treatment for algae. Let me show you how an Algaecide works.
Algaecides are based on different materials. Mostly, algaecides are copper-based i.e. copper chelates or copper sulfate. These chemical compounds work like a medium to reduce algae in a proper way. Some algaecides are based on herbicide endothall to stop the regular cellular process of algae. A few algaecides are based on sodium carbonate peroxyhydrate.
When you use any of them, it will disrupt the energy transport to stop the cell division in algae. So, it’s not possible for algae to continue the production of cell proteins.
Note: If you are using the hard water i.e. the water that contains high metal content, your pool will get oxidation due to the copper-based algaecides. As a result, oxidation can stain your pool instantly. In such condition, use a copper-free algaecide to keep your pool surface stain-free.
Common Types of Pool Algae
There are four common types of pool algae. Let’s see what they are:
Green Algae: Green algae are the most common type of algae that even grow in the sunlight on damp and warm places. It grows when you don’t clean the pool surface after using. Have you experienced of swimming in a lake? What happens when you don’t wash your swimsuit after using in the swimming? Of course, the swimsuit surface will get green algae.
Yellow Algae: It’s also known as mustard algae. It’s rare but grows when your swimming pool lacks sunlight. It’s persistent and annoying when grows. It’s not easy to eradicate without using a good quality algaecide.
Black Algae: It’s the most complicated type of algae and you can’t get rid of it easily. These are the strain of blue-green algae and it grows in plaster pools. It can’t be eradicated with an ordinary algaecide. You need to use thick multi-layered algaecides to protect the plaster pools from them.
Red Algae: It’s tinted with yellow carotenoids. It’s also known as pink algae/slime. These algae can live without sunlight in damp places.
I will start with our Poly Algaecides. Our Poly 30 is a great maintenance product. This algaecide has a positive electrical charge that attaches itself to the negative charges of dirt and debris and allows this debris to get caught in your filtration system easier. Our Poly 60 is twice as concentrated and is good at treating algae in the same way. The positive charge is attracted to the negative charge of existing algae and clumps it together, making it easier to vacuum out of the pool. This algaecide works well on easy to beat, green algae. It’s compatible with salt-free and saltwater pools.
If you want to keep the water pools algae-free, keep the pool surface clean and maintain the weekly cleaning schedule. Don’t keep the surface damped to avoid algae growth.
Precautions: Brush the pool surface daily to clean the dirt and debris because it triggers algae. Furthermore, you should test weekly your pool to maintain chlorine and pH level at optimal levels.
Concentrated Red Algaecide
Our Concentrated “Red” Algaecide and Algae Stop 10, are ammonium-based algaecides. It’s used to eradicate the blue-green algae. This type of algae is colored with yellow carotenoids. When your pool lacks sunlight and removes chlorine.
This is mostly used in small doses, and if used in excess, it can cause foaming when the water is agitated, but it will eventually oxidize out of the water. This algaecide works great in part with chlorine and helps enhance the performance of chlorine. The ammonium splits open the algae cell and allow the chlorine to kill the algae. This is probably the most popular and least expensive algae preventative and treatment, but the most unfavourable because of the chance of foaming.
You can use it in salt-free and salt-water pools because it doesn’t create any side-effects.
Copper-based Algaecides (Algae Krush & Algae Break 90) are the most effective ways of killing and preventing algae. It is great at treating hard to beat black algae and works on all types of algae. But be leery of some Copper-based algaecides that are not purchased from Viscount Pools of Metro Detroit, because they may cause staining in pools, especially Gunnite pools. Talk to a pool professional to ensure that the Copper algaecide you are using has a sequestering agent, to prevent any staining. All of our Copper-based algaecides contain sequestering agents. These algaecides leave a residual of copper in the water and continue to prevent algae for 90 days, as long as proper chlorine levels are consistent.
Algaecide for Mustard Algae
Our last Algaecide is used strictly for treating Mustard Algae. Mustard Algae tends to embed itself to the surfaces of the pool, making it very difficult to remove or brush. Yellow Klear and Yellow Cure are Sodium Bromide based algaecides and help detach the algae. It is then activated by shocking the pool with chlorine. We like using this algaecide in part with a clarifier.
Dosage rates and concentration vary depending on the algaecide. For best results always bring in a water sample to be tested by our certified water testing professionals. Each algaecide works only when the balancers are within range, and some require a high Ph in order to work.
Feel free to talk to our knowledgeable staff to help reduce any factors that can contribute to algae growth. We can discuss the many preventative measures, to ensure that your water will always be sparking. We can even help you reduce those environmental factors such as Phosphates, and help you maintain low phosphate levels.
