Algae and mold can be a huge problem for swimming pool owners, and with our particular Colorado climate, combined with variation in a pool’s chemical levels, they can turn up when you least expect it. As winter turns to spring and the weather starts to warm up, you’re probably starting to think about how to get your pool into tip top summer shape so it’s important you know what you’re looking for.
What’s the difference between mold and algae?
Algae are single-celled plant forms that consume the process of photosynthesis to manufacture its food sources. Algae are basically a type of plant that thrives on sunshine and moisture. Mold typically forms in damp, warm and poorly maintained areas.
Mold is far more dangerous and difficult to remove – mostly because it is often caused by deeper issues. Due to algae’s microscopic size, it takes literally millions of them to accumulate to be noticed by the naked eye, and by that time it can be very costly to fix.
As with mold, the best way to eliminate algae is through prevention through salt water chlorine systems.
Molds in Your Pool
White Water Mold is a naturally arising fungus that has a white mucous or tissue paper like substance. White Water Mold produces a substantial shielding coating providing the bacterium with an abnormally high level of protection that is very resilient against chlorine and bromine based sanitizers.
It can remain a toxic even after treatment as it can survive on the surface of plastics like pool toys, ladders, steps, floats, pool cleaner parts and skimmer baskets. White Water Mold is usually triggered by inappropriate water and pool maintenance, environment, and poor circulation. It will require professional mold removal, to ensure it is eradicated.
Black Mold will grow where there is high moisture and humid temperatures, and there are most likely plenty of areas around your pool where mold will love to grow. If you are concerned that there is excessive mold growing around your pool area, it’s best to contact the professionals to have it tested and treated, to ensure it doesn’t spread.
Algae in your pool
The most common form of algae in swimming pools is “green” algae which will vary in color from blue-green to yellow-green to dark-green. It will most often be seen floating in the water or clinging to the walls of your pool. It is relatively easy to treat with brushing, shocking, and chemicals.
Blue-green algae (aka Black Algae) forms in cracks and fissures on pool exteriors, especially on plaster surfaces. Blue-green algae would typically be found in the shady areas of your pool and is notorious for its heavy slime layer.
Mustard algae are a chlorine resilient form of green algae which appears in a yellowish green to brown color. It often looks like dirt or sand on the bottom of your pool, and will need proper treatment by a professional.
Whether you are buying, or renting a property with a pool, and want to ensure your home or building is mold free, a professional mold testing service as well as a pool maintenance team is most important.
