Algae RemovalAlgae removal is needed when your pool has serious cases or especially stubborn algae – particularly for black or yellow algae – you might need to apply aggressive methods.

 

 

 

There are three different stages of algae in which various amounts of shocks will be needed, these are:

  • Light green algae – If your pool is light green, you will need to double shock it so as to kill the algae. 500 grams of shock treats about 40,000 liters of water. Therefore, if your pool holds about 40,000 liters of water or less, you will require 1kg of shock (2 sachets). If it holds 80,000 liters of water, you will require 2kg of shock (4 sachets), 3kg for 12,000 liters, and so on.
  • Dark green algae – If your pool is dark green, you will need to triple shock it so as to remove the algae. Here, if you have 40,000 liters swimming pool or less, you will require 1.5kg or 3 sachets of shock. 3kg or 6 sachets for 80,000 liters or less, 4.5 kg or 9 sachets for 120,000 liters, and so on.
  • Black green algae – This is the toughest stage of an alga. If you have an alga from the “black kingdom”, you will need to quadruple the shock. Hence, if your pool holds 40,000 liters of water, add 2kg or 4 sachets of shock. For 80,000 liters, add 8 sachets or 4 kg, 6 kg or 12 sachets for 120,000 liters, and so on.

Note:

  1. These aren’t different types or forms of algae, they simply different amounts. The more organisms in your swimming pool, the darker the color will be. I have come across pools which are dark due to algae infestation.
  2. If your pool features a vinyl liner, ensure that you dissolve each ½ kg (1 sachet) bag in its individual bucket of water before adding it to your pool. This will prevent the liner from being destroyed (bleached) due to shock.
  3. Don’t pour the substance through the skimmer – shock has calcium hypochlorite which mixes with trichlor in chlorine to form an explosive green gas.
  4. Finally, always shock during the night. Chlorine burns off one ppm every hour during the day (sunlight) to run below the required level to kill algae.

Here are tips to help you prevent algae:

  • Don’t let fertilizer enter your pool
  • Maintain the recommended pH level of between 7.4 and 7.6
  • Brush the pool regularly
  • Maintain the chlorine level at about 2-3 ppm
  • Keep your filter clean
