Understanding Black Mold

Black mold is a type of fungus that thrives in damp environments, including swimming pools. It appears as dark patches and emits a musty odor, which poses several problems.

First, it might cause health issues such as respiratory problems, allergic reactions, and skin irritations, particularly in vulnerable individuals. Second, black mold can damage pool structures, eating away at liners, tiles, and grout, leading to costly repairs.

It may also cause permanent staining, affecting the pool’s appearance and potentially decreasing property value. Lastly, black mold might impact water quality by introducing harmful bacteria, disrupting chemical balances, and clogging filtration systems. This makes the water unsafe for swimming and more difficult to maintain, potentially increasing maintenance costs and effort.

Identifying black mold in your pool

Black mold in pools appears as dark spots or patches on surfaces, which may be black, dark green, or brown, and often have a slimy or fuzzy texture. It commonly develops on pool walls—particularly around the waterline—floors, corners, and areas around fixtures like ladders and lights.

A musty odor often accompanies mold. Discolored areas spreading across these surfaces, along with changes in water quality such as cloudiness or a greenish tint, could indicate mold growth. An increased need for chemicals, particularly chlorine, may further signal a mold problem.

Preparing for mold removal

Before tackling black mold, gather the necessary supplies: a stiff-bristle pool brush, chlorine shock, algaecide, safety gear such as gloves, goggles, and a mask. Ensure the pool area is well-ventilated, and keep pets and children away during the treatment.

Next, test and adjust the pool water’s pH, chlorine, and alkalinity levels to ensure optimal treatment. Remove any visible debris from the pool and turn off automatic cleaners to prevent the spread of mold spores.

Steps to eliminate black mold

Start by thoroughly scrubbing the entire pool surface, giving extra attention to the affected areas. Use firm, circular motions, working from the shallow end to the deeper sections to ensure a thorough clean. 

Once you’ve scrubbed the pool, shock it with a higher-than-normal dose of chlorine, distributing it evenly around the pool’s edge. After shocking the pool, run the pump continuously for at least 24 hours to help circulate the chlorine. 

Then, apply an algaecide specifically designed for black mold and adhere to the product instructions. Keep the pump running to distribute the algaecide evenly and to help remove dead mold particles.

As the treatment progresses, ensure the filter remains operational and clean it frequently, as it may become clogged more quickly. Monitor the water clarity daily and continue filtering until the water is crystal clear. 

Lastly, test the water chemistry and adjust it to normal levels. Add any necessary chemicals slowly and retest after each addition to maintain optimal balance.

How to Get Rid of Black Mold on Pool Deck

To effectively remove black mold from a pool deck, first put on some protective gear and gather necessary supplies, such as a stiff brush, a cleaning solution like bleach or vinegar, and a pressure washer, if available. Next, dry brush the moldy areas to loosen the spores.

Once the spores are loosened, apply the cleaning solution and allow it to sit for 10-15 minutes. Then, scrub the area vigorously to ensure thorough cleaning. 

For larger areas, using a pressure washer set to medium can be particularly effective. Rinse the deck well after scrubbing and let it air dry.

After the deck has dried, inspect it for any missed spots and repeat the process if needed. To prevent future mold growth, it’s important to improve drainage, regularly clean the deck, and consider applying a mold-resistant sealant.

Preventing Future Black Mold Growth

To prevent black mold growth in your pool, it’s crucial to maintain proper water chemistry. Regularly test and balance chlorine, pH, and alkalinity levels. 

Furthermore, running the pool pump for at least 8-12 hours daily ensures good circulation. Additionally, regularly cleaning or backwashing the filter system helps maintain its efficiency.

Weekly maintenance is also essential. This includes brushing the walls, vacuuming the pool floor, and skimming debris from the surface. 

Keeping the pool deck clean and ensuring proper drainage prevents standing water, which can contribute to mold growth. Using a pool cover when the pool is not in use reduces humidity and evaporation, further discouraging mold.

Moreover, outdoor pools benefit from trimming nearby vegetation, allowing more sunlight to naturally inhibit mold growth. For indoor pools, consider using a dehumidifier and ensuring proper ventilation to control moisture levels. Maintaining a consistent water temperature is important as well since warm water can accelerate mold growth, so avoid overheating the pool.

When to Call a Professional

Knowing when to call a professional for mold removal depends on several factors. Expert assistance is essential if the affected area exceeds 10 square feet, is hidden in hard-to-reach spots, or involves toxic species like black mold. Health concerns like persistent respiratory issues also justify seeking professional help. 

Specialists are particularly necessary after flooding or ongoing moisture problems, as they can address the mold and its underlying cause. Also, rental properties or insurance claims might require a professional assessment and remediation.

If DIY attempts fail and mold keeps recurring, it’s time to call in experts. They have the tools, knowledge, and techniques to remove mold, improve air quality, and prevent future growth. This ensures a safe and healthy living environment.
