Black Algae in Pool
Black spot algae in pool
Don’t drain your pool to remove black spot algae because it will simply come back again! Draining your pool is a waste of time and money because the algae also lives in the pipework, heaters, pool lights, filter, and pump. So, once the pool is acid-washed and refilled, the algae in your pool equipment will blow back into the pool and start spreading again.
We have removed black spots from dozens of pools that had already been acid-washed just a few months earlier!
The best way to fix black spot algae for good is to use products that are strong enough to do the job properly. Don’t worry, we’ve done all the hard work to find the solution, so you don’t have to waste your time and money.
6 Signs of Black Spot Algae
Black Spot Algae and mustard algae can be completely removed using our treatments on any pool finish, including plaster, Quartz, Marcite, Ptebbletec, fully tiled or fiberglass pools. We can permanently remove Black Spot and other algae from swimming pools without draining the pool.
If you’re unsure of the type of pool stain you have, please call us. Remember, adding the wrong treatment can make it much worse and spread faster so feel free to call if you are unsure.
- Individual black spots on pool surface
- Spreading and multiplying over time

Fix black Spot Algae without draining
Our treatments offer a fast and simple solution to removing black spot algae in swimming pools, without draining the water. These proven treatments kill algae and provide ongoing protection to stop black spot algae from coming back.
Of all the pool issues we treat, Black Spot Algae is the most likely to return once removed. This is why good quality products and powerful prevention algaecides are so important.
Our products kill all types of algae and bacteria that standard chlorine levels can’t touch. Typically, our algaecides transform your green pool water into clear water within 48 hours and fully eliminate black spot, green algae, and mustard algae in just a few weeks. This is because our two-step algicides work together to remove algae. The first removes the protective biofilm from the algae’s surface. Then, the second product penetrates the algae to kill it off at the roots. Remember, without these two steps, the algae will just come back!
How our black spot treatment works
Black spot algae is very stubborn and likely to come back quickly if not treated properly. Skip any of these critical three steps and you have wasted your time and money.
- Penetrate Protective Biofilm. Black spot Algae is protected by a thin biofilm layer that shields itself from chlorine and most algaecides. This is why black spot can resist almost anything. Our first step algaecide dissolves this biofilm, exposing the algae to our treatment.
- Long Life Algaecide. With the biofilm removed, our second step algaecide penetrates the algae’s roots to kill it completely. It is also a long-term preventative treatment so it stops new black spot sporesow spores.
- Powerful Long-life chlorine. Our high-strength chlorine works with the algaecides while they do their job, helping the water fight the black spot directly and pushing both treatments to perform at their highest level.
These vital steps are all completed with our products.

Causes of Black Spot Algae in pools
Algae in swimming pools primarily stems from two issues:
- High phosphates. Most pool experts agree that removing phosphates from the water makes it hard for algae to survive. Phosphates are a critical factor, acting as a primary nutrient that fuels algae’s survival.
- Low Chlorine. Low chlorine levels help black spot algae growth because there is not enough sanitizer to kill or prevent the algae from taking hold. Black spot algae is particularly resilient, forming a protective layer over itself and rooting deeply into pool surfaces. When chlorine levels are too low or inconsistent, the sanitizer can’t penetrate this tough barrier or eliminate the algae spores.
- High leaf load. Trees surrounding the pool carrying black spot algae can fall into a pool and reintroduce to the pool. This is often why it returns to the same pool time and time again.
To kill black algae, strong, undiluted algaecides that pack the strength to kill tough algae growth are required. Cheap algaecides are mostly just colored water, lacking enough active ingredients needed for the job. Our undiluted products have no added water or coloring to weaken their algae-killing power.
We suggest tackling black spot algae quickly. If left untreated, its roots penetrate plaster pool surfaces, causing permanent discoloration.
Types of Algae Found in Swimming Pools
Green algae is the most common and fastest-growing algae in swimming pools. It often turns your pool water green or cloudy overnight! It usually starts in corners, steps or areas where automatic pool cleaners can’t reach. Furthermore, low chlorine levels, warm temperatures, and very high phosphates are the perfect combinations for algae growth. We can remove green algae in less than 48 hours and keep it gone.
Mustard Algae is usually easy to brush off the walls and floor of your pool, but it will often quickly return. It grows in shady areas of the pool , which are protected from sunlight or areas of poor circulation. So, just like black spot, yellow algae is somewhat resistant to normal chlorine levels. Our treatment will remove mustard algae in less than 72 hours. If you cannot brush the algae away, there is a chance that you may have a stain instead. We can help you with that.
Black spot algae is unique because it grows on the walls or floor of your pool in spots, often in areas with low circulation. It will not brush away like other algae. This algae type spreads and is often mistaken for mold because it forms dark spots on the pool surface. Therefore, we suggest that you act on this type of algae quickly, as its roots (algal spores) can penetrate the pool plaster and cause permanent damage and discoloration to your pool interior. Black spot algae forms a protective layer that makes it resistant to chlorine. Our quality process and products will remove it within a few weeks. Remember, some pool guys mistakenly believe that black spot can NEVER be completely removed without draining and acid washing. However, black spot CAN be removed and we do it regularly. IMPORTANT NOTE: DON’T DRAIN YOUR POOL TO REMOVE BLACK ALGAE!
If you have black spots in a fiberglass pool, please contact us for further information.
Unlike other algae, pink slime is actually a bacteria, not algae. So it often appears around skimmer boxes, lights, ladders, and other areas of the pool. If not treated promptly, it will continue to slowly spread around the walls and floor of your pool. We’re able to remove pink slime algae for you with our products. Remember, it is not very common in America.
