How To Kill Black Algae: Step

Killing black algae in your pool can take some time. Youll likely need to disinfect every affected surface while scrubbing everything thoroughly to dislodge the algae and break its heads. While some people prefer to drain their pool to make this step more manageable, its not required. Here are the steps you can take before draining your pool.

Scrub The Sides And Surface Until It Gleams

Make like your Auntie Debbie and brush that pool! Be aggressive. Black algae are stubborn, and youll need to put your back into it. Brush at least 3-4 times a day for as long as you can before wearing yourself out.

Buy a stainless steel algae brush, they are specially designed to cut into algae, making scrubbing a lot easier. Remember, this is going to be the difference between a hygienic and safe pool or repeat occurrences so buying the right tools to help you do a good job will always be a worthwhile investment.

Sanitize Like Theres No Tomorrow

If you or anyone you know has had a cheeky little swim in the contaminated water, make sure you ask them to wash their swimsuits as well as any floats or toys that have been in the pool.

If it can go in the washing machine, so much the better, this should kill the algae. Hand washing your swimmers might not be enough.

As for toys, floats and armbands, use bleach to sanitise them and scrub them with a brush just to be on the safe side. Do the same with any equipment you use for maintenance, including your filter.

Basically, anything that has touched or been in the pool will need a good clean.

How Long After Adding Algaecide Can You Swim

Black Algae Treatment, Get Rid of Black Algae in Your Pool

When you add algaecide or basic chemicals to maintain levels like alkalinity and pH in your pool water, you usually only need to wait a short timejust about 20 minutes to an hourbefore you can get back in the water. However, with shocking agents, youll need to wait much longer before you swimusually about 24 hours or until the levels are around 5ppm.

If you hire a pool professional, they can regularly add algaecide and other key substances to the pool, like cyanuric acid. Plus, they can best advise you on how long youll need to wait before you can get back in the pool and can provide ongoing pool cleaning services.

Beyond contacting a professional, some other preventative steps you take to avoid black algae growth include washing any items you use in a lake or other natural body of water before using them in the pool. This should involve a heavy wash because black algae is microscopic and difficult to remove with a basic rinse. Wash all swimming suits in the washing machine and use a bleach solution to scrub down inflatable tubes and pool toys.

Preventing Black Algae Infections

As you may have realized, the most efficient way to take care of black algae infestations is to prevent them from ever happening in the first place! While you cant always prevent the spread of the black algae bacteria, if you keep your pool at set parameters that discourage black algae growth, you can save yourself enormous trouble.

The first thing you can do to help prevent black algae formation is to discourage black algae spores from ever reaching your pool. When your pool is not in use, cover it thoroughly to prevent airborne spores from landing in your pool.

Never swim in your pool with swimsuits that were just in a lake or the ocean! Black algae spores are plentiful in nature, and they often hitch a ride on swimsuits and find their way into your pool. Make sure to wash and sanitize any swimsuits thoroughly before wearing them into your pool .

Additionally, keep in mind that pets that have been in contact with natural water sources can also act as carriers. For this reason, you should consider not allowing your pets into your pool at all.

Finally, the more you stay on top of your pools chemistry, the less likely you will have a black algae infestation break out. As with any organism, the more regulated your pools aquatic environment is, such as pH, alkalinity, and chlorine levels, the less likely outside bodies are to thrive there. A robust and functional filter that you run often can reduce risks too.

In The Rare Case That The Algae Does Bloom Follow These Quick Steps To Learn How To Kill Algae In A Pool:

Test and balance your water chemistry. However, when fighting algae, Leslies recommends keeping your pH slightly higher than usual; somewhere between 7.8 and 8.0.

Depending on your type of filter, clean or backwash the filter to remove debris and contaminants. You will want to set the filter to run 24 hours a day while treating your pool for algae.

Brush the pool walls thoroughly, especially those areas with visible algae blooms.

Be sure to use a brush that is safe for your pools. Wire brushes are great for plaster and gunite pools, but should never be used for vinyl, fiberglass, or tiled pools. If you do not own a plaster pool, using a nylon brush will let you safely brush your pool walls.

Add a powerful shock, like Power Powder Plus or Leslies Chlor Brite. Follow the directions on the shock for proper dosage amounts. Large amounts of algae may require you to add up to three doses of shock over a 36-hour period. When using large amounts of shock to kill algae, water may become cloudy. This should not be a problem, and the water should clear up after running the filter.

Wait until the chlorine ppm has fallen below 5.0. After this, add a pool algaecide like Leslies Algae Control and brush the pool again.

After brushing, vacuum the pool. If large amounts of algae are suspended or floating on the surface, it may be a good idea to add a flocculent like Ultra Bright. This will cause the particles to bind together and fall to the bottom so they can be vacuumed easily.

Why Do You Have Black Algae In Your Pool

Simple. Someone swam in a natural body of water like a river, pond, lake, or the ocean, didnt wash their swimwear afterward, and then wore that same swimwear into your pool.

Maybe that was you, and you did remember to wash your swimwear in between, but forgot about that inner tube you used to float down the river, and then tossed it into your pool unwashed. You just put out the welcome mat for black algae in your pool.

Its less likely, but black algae can also enter your pool via airborne spores.

Now what? Well, the first step to getting rid of black algae is understanding what it is, because guess what? Its not algae at all.

What Causes Algae To Form In A Pool

How To Get Rid Of Black Algae In Your Pool

The main cause of algae in a swimming pool is low free chlorine level. Algae is rampant in hot and humid climates or during the summer, simply because chlorine reduces faster as water temperature increases leaving your pool vulnerable to algae and bacteria.

As such, the only way to keep algae and bacteria away is to maintain recommended FC level of 3ppm all the time by adding chlorine whenever it drops below 3ppm and this should be done on a daily basis. But don’t think, even for a moment, that maintaining chlorine levels is enough: You need to maintain an appropriate balance of all chemicals in your pool because they affect how long chlorine lasts in your water.

Most chemicals used in the pool, such as pH chemicals, sanitizers, alkali, calcium, stabilizers, and more, will affect how chlorine works and how it is consumed. For this reason, the only perfect way to avoid algae or cloudy water is to constantly maintain the correct chemical balance in your water, which means using an accurate pool water testing kit.

Brush Your Pool Again And Again

Brush your pool at least 3 to 4 times a week, concentrating on where you first spotted the algae. Remember, black algae has deep roots that can be embedded into your pool walls. It may look like its gone, but its probably still there. Just keep brushing. Continue brushing for several days after you see it starting to dissipate.

This is, however, not a guarantee. Black algae is relentless and could continue to infect your water. If it does, you know how to kill it, just be more aggressive next time. Perhaps consider an additional dose of acid and chlorine and constant brushing.

Don’t forget to use some Black Spot Remover to make sure that the not only does the black algae brush off easier, but they stay off as well.

Keep An Eye Out For Stragglers

Over the next few days , keep a close eye on your pool for any signs of black algae returning. Its possible that, even with all that shocking and brushing, you may have missed a teeny-tiny bit that will start to grow again. Were talking about bacteria, remember. Its microscopic.

If you do see a small spot reappear, brush it off, scrub the spot with a broken chlorine tablet, and then give your pool a normal dose of shock.

After all that, were betting you dont ever want to see the smallest spot of black algae in your pool again, right? So make sure you do everything you can to keep it out.
