If your pool is turning green, it's likely due to an algae bloom, which can be caused by several factors including inadequate chlorine levels, poor circulation, insufficient filtration, or high nutrient levels in the water. Here are some steps to help combat and prevent a green pool.
Check and Adjust Chemical Levels
Chlorine Levels: Ensure that the chlorine level is within the recommended range (typically between 1-3 ppm). If it's too low, add more chlorine.
pH Levels: The pH should be between 7.2 and 7.8 for optimal chlorine efficiency.
Alkalinity Levels: Maintain total alkalinity between 80-120 ppm to stabilise the pH.
Calcium Hardness: Ensure calcium hardness is between 200-400 ppm to protect surfaces and equipment.
Run the Filter Properly
Filter Operation
Run your filter continuously until the water clears up.
Filter Cleaning
Clean or backwash your filter as needed to ensure it's functioning efficiently.
Shock the Pool
Perform a pool shock treatment by adding a shock oxidiser (non-chlorine or chlorine-based) to oxidise any built-up contaminants and reduce combined chlorine levels.
Algaecide Application
Apply a pool algaecide specifically designed for pools according to the manufacturer's instructions. This can help kill existing algae more quickly.
Brush Pool Walls and Floor
Regularly brush pool walls and floors to dislodge algae that cling to surfaces.
Circulation Improvement
Ensure that your pool water is circulating properly by running pumps continuously and checking that jets are functioning correctly.
Reduce Nutrient Sources
Algae feed on nutrients like phosphates and nitrates found in swimmers' sweat, sunscreen, fertiliser runoff, etc. Use a phosphate remover if necessary and regularly test for nitrates if you suspect they might be contributing.
Regular Maintenance
Regularly test your water chemistry at least once a week.
Perform routine pool cleaning tasks such as vacuuming leaves off the bottom of the pool.
Avoid letting swimmer load exceed recommended limits as this contributes to nutrient levels.
Consider Professional Help
If you're not comfortable addressing these issues yourself or if your attempts don't yield results, consider hiring a professional pool service technician who can assess and treat your pool effectively.
