4 Causes Of Algae Build Up In Your Pool

Staying proactive with algae removal is imperative because not only is it unsightly, but it can also make your pool off-limits. Some brave souls who dare to swim in a pool with algae end up with skin and ear infections and worse. Algae is a common yet frustrating issue that requires professional cleanup. To prevent this, you need to first understand what causes algae. Check out some reasons that we have explained below.

Greater Alkalinity

Get the water in your swimming pool tested to check its alkalinity, calcium, and cyanuric levels. If the test shows that the water has a high pH value, there is greater alkalinity. Alkalinity coupled with low chlorine levels can foster algae growth, so make sure your pool water has the right combination of minerals and other components for the correct pH balance.

Lower Chlorine Levels

When chlorine mixes with pool water, it forms a weak acid called hypochlorous acid, which kills germs and bacteria such as E. coli and salmonella that can cause diarrhea and other illnesses. Thus, inconsistent or very low chlorine levels in your backyard pool can promote algae growth.

Keeping swimming pools chlorinated is the most popular technique used worldwide for pool cleaning and sanitation. Different chlorine-based compounds can be used for this purpose, including chlorine gas, sodium hypochlorite, and chlorinated isocyanurates.

Insufficient Circulation

A significant reason for algae growth in your swimming pool is poor water circulation. Water continually circulates through the pool, going from the pool into the filter and back. However, if the water filtration system is not working properly or if you are using a small filter that cannot meet the needs of your pool, then dead spots might occur in certain parts of your pool. Dead spots or low-flow areas with little to no water circulation, which make them breeding grounds for algae. Algae grows in still water, so while your filter maintains ideal function, you are safe from algae. Regular testing needs to be done, especially in larger pools, to determine if the water is flowing consistently through all pool areas to eliminate dead spots or low flow.

Poor Filtration

The water in your swimming pools needs to be filtered regularly. Do not run your pool filter for a limited amount of time; ensure that you are running it for a sufficient time period. Also, make sure you have an appropriately sized filter installed in your pool. A water filter that is not working properly is mostly off or does not meet the pool’s cleaning requirements can become a cause for algae growth.

Water discoloration is an obvious indicator of algae growth, so if your water is turning yellow, green, or blue-black even after avoiding the four top causes mentioned above, then you are in urgent need of professional algae removal services!
