How Black Algae Is Specifically Treated

What You Should Know About Swimming Pool Algae

The treatment for black algae is very similar to the treatment used for yellow algae. Once youve analyzed the water, it is essential that you brush the algae thoroughly, which is particularly important with black algae in order to break the slime layer. If you skip this step, the rest of the treatment wont work as intended. As with yellow algae, you will likely need to heavily shock the pool water with chlorine if you want to eliminate the algae. High amounts of Algaecide 60 should be added to the water as well. This process should be repeated at least three times. Make sure that you brush the pool after each treatment.

What Causes Swimming Pool Algae

Algae spores enter your pool all the time. Wind, rain, or even contaminated swimsuits and pool cleaning tools can carry spores. When conditions are right, an algae bloom can occur in a matter of hours.

These conditions include out-of-balance water, warm temperatures, and sunlight. The presence of nitrates, phosphates, and carbon dioxide can spur their growth. A lack of adequate circulation, filtration, and sanitation is usually a contributing or even primary cause of pool algae.

Should Phosphates Be Removed

Some pool professionals and chemical salespeople sell the idea that algae bloom can only be controlled by removing phosphates from your pool. Because of this, many pool owners overspend on swimming pool phosphate remover, thinking that this solves the problem. Because there are other components factored into the relationship between phosphates and algae, merely using a swimming pool phosphate remover is not the answer.

How To Remove Algae From Your Pool Water

What Causes Green Pools & Algae Growth in Swimming Pools? We Can Help Explain – Chlorine King

Removing algae from your pool involves several components. First, double-check that your pools sanitation, filtration, and circulation systems are all working. Check your pools chemistry too. Make sure to vacuum your pool at least once a week to remove debris if you dont have a self-cleaning pool. For an isolated algae bloom, use granular chlorine to treat it. You can also get a brush, apply algaecide to the water, and scrub. If you have free-floating algae, youll have to shock your pool.

To start, balance your pool water to get your pH between 7.1 and 7.3. Check your filtration and pump systems, and shut off your heater if you have one running to lower the water temperature. Adjust the valves on your pump and let it run for 24 hours. You can stir the algae up by switching your pool cleaners on. Get a stiff bristled brush and scrub at your pools walls and floors every day, and vacuum your pool. For green water, apply a flocculent and shock it.

Shock the pool vigorously to get rid of suspended algae. You should add enough shock that it turns your pool water a blue/grey colour. Youre aiming for 30 ppm of free chlorine, and youll need roughly 2 to 5 kg of shock for every 10,000 gallons in your pool. The day after you shock your pool, test the chemical levels, paying close attention to your pH and chlorine. If your chlorine is below 5 ppm, you have to shock it again.

If algae have been an ongoing problem in your pool for several years, you may do well to drain the pool. Many years of algae can build up dead algae cells and lots of other solids in the water that contribute to its rejuvenation. Acid wash or chlorine wash the pool to kill the roots of the algae embedded in rough plaster.

For pools with repeat algae blooms, you may also test for phosphates in the pool. Look for sources of contamination from fertilizers or soil washing into the pool during heavy rainstorms. Also, look closely at the water balance and sanitation practices you have in place.

What You Need To Know About High Phosphates In Your Pool Or Spa

If you own a pool or spa, you understand the delicate balance of keeping the water clean and algae-free. For many pool owners, a swimming pool phosphate test kit is a fact of life to ensure water purity.

What Causes Algae Problems

Algae spores constantly enter the pool, brought in by wind, rain or even contaminated swimsuits or pool cleaning tools. When conditions are right, an algae bloom can occur in a matter of hours. These conditions include out of balance water, warm temperatures, sunlight and presence of nitrates, phosphates and/or carbon dioxide. A lack of good circulation, filtration and sanitation is usually a contributing or the primary cause of pool algae.

Algae are a living aquatic creature that multiplies rapidly on warm, sunny days. Containing chlorophyll, algae utilizes photosynthesis to grow. That is, they take in carbon dioxide and expend oxygen as a byproduct. Algae can grow in the shade or sun, but most pool algae strains need some light to grow.

Algae need food to survive, and in a swimming pool there is no shortage of tasty food for algae. Nearly every contaminant or windblown speck of dust can feed pool algae. In pools with high bather count, or pools with high levels of debris or dissolved solids, algae has a smorgasbord of nutritious food. Even the dead cellular remains of previous algae blooms provide sustenance to future generations of pool algae.

Algae are always present in swimming pools, even clean and blue pools, at a microscopic size. It waits patiently for the opportunity to bloom â when the chlorine level dips and the pH rises or the pump or filter is not operating effectively.

Keep Your Filter Clean

How to Eliminate Algae in Your Swimming Pool

Pool Algae Health Issues

Is algae in the pool harmful, or can you swim in a pool with algae? You can, but you may not want to, especially for young children, or others with under developed or compromised immune systems.

Small patches of algae here or there is not a health concern, but if the pool is having a full blown algae bloom, with low water clarity and low chlorine levels, it may not be healthy for swimming.

If the chlorine is not killing the harmless cyanobacteria algae, the chlorine is probably also not killing harmful pathogenic bacteria that may also be present in the water.

How To Get Rid Of Green Algae In Swimming Pools

Causes of Green Algae in Swimming Pools

If you have green algae in your swimming pool, there are several methods you can try to get rid of the problem. If your pool water is green and you can see visible clumps of algae floating in the pool, you will need to try chlorine cleaning first because your pool didnt have enough chlorine to kill the algae on a daily basis. Chlorine might also be used at the beginning of the season. Using a large dose of chlorine is called shocking, and it will return your pool to a more sanitary state. Shocking the pool usually takes from one to three days. But, be prepared, it may take as long as a week if your pool was in poor sanitary condition. Before you use the chlorine, however, make sure you vacuum or sweep up all the algae on the bottom of the pool, as well as the off the pool walls and around the ladders.
