Algae is a very common pool maintenance problem. If your water is green or algae is growing on the sides of the pool or at the bottom, it means that your pool is contaminated with algae. These microorganisms can quickly spread and over the course of hours destroy your water chemistry, turning a pool from pleasant and delicious to terribly dirty and smelly. We'll show you how to deal with them.

Steps

Method 1 of 4: Green Algae

1. 1 Use a pool treatment to stop the growth of green algae. Add as much hypochlorite as needed to give the pool a cloudy gray color. Clean the sides and bottom and completely drain the pool.
   • Clean the filter again if the pressure gauge indicates it is necessary.
   • When the chlorine level is less than 5ppm, add algicide and clean the pool again. When all the nasty things have settled, brush the pool with a brush.
   • You can clean through a vacuum instead of a filter, so that later you do not break through the filter. If you need to filter the pool, rinse the filter again when finished.
   • Check pH and rebalance as needed.

Method 2 of 4: Black Algae

1. 1 Dealing with this is difficult. Black algae is stubborn and pervasive and will take a dedicated effort to rid your pool of them.
2. 2 Use a pool remedy as described above. Add as much hypochlorite as needed to give the pool a cloudy gray color. Clean the sides and bottom and completely drain the pool.
   • With black algae, pool cleaning is a crucial step. You have to break down the tough protective layers of algae so that the algicide can get in and do its job. Pumice stones are good for this step.
   • Any algae will weaken during pool cleaning and must either be brushed off or the pool completely emptied with a vacuum, filtered and rinsed immediately afterwards.
   • Granular trichloride works well to sprinkle on any affected areas on the bottom of the pool. Trichlor sticks or tablets will remove algae that are clinging to the pool walls and destroy their roots.
3. 3 Use an algicide. After killing the algae with a brush and pumice stones, add a dose of copper algicide to the pool.

Method 3 of 4: Permanent Algae

1. 1 Clean your pool. Not only with a net and a brush, but completely drying and filling the pool.
   • After the pool is empty, flush it with water or acid to clean the walls and destroy live and dead algae on the surface and ingrown into the pool.

Method 4 of 4: General Pool Hygiene

1. 1 Examine the entire pool. Use a net to remove any visible dirt and debris from the surface of the pool and inside. If you have a water brush, also use it ..
2. 2 Check the pH level in the pool. Whether you are struggling with algae or not, this should be checked at least once a week, or more often if you have time to do so. The PH factor of a normal pool should be between 7.2 to 7.4. (The human eye has a pH of 7.35). If it is outside this range, the water must be treated.
3. 3 Adjust the pH level in the pool. Pool chemicals and chlorine are designed to work best within the 7.2-7.4 range. Chlorine is not very effective in high pH water.
4. 4 Check the filter system. Make sure it is clean and working well, but rinse gently if necessary.
5. 5 Make sure your entire system is working very efficiently. For quality algae prevention, make sure you have excellent filtration, sanitation and circulation in your pool.
   • Change sand filters every 5-7 years.
   • Change Baquacil filters every 2-3 years.
   • Cartridge filters should be replaced every 1-2 years
   • D.E. filters should be changed every year. Spray residues in a spray, soak in a 10: 1 solution of water and bleach, rinse and replace.

Tips

• Controlling the pH of the water and stirring the water as needed can prevent algae outbreaks. If you have a problem with algae, or to prevent such a problem, a pool algaecide is usually added. Algicide, which is formulated on non-metallic substrates, will prevent swimmers from discoloring their hair.
