As a pool owner, there’s nothing worse than looking out at your pool and seeing green water. It can happen even to experienced pool owners, but it's easily reversible once you know what caused the issue in the first place.
The pHin experts put together a list of reasons why pool water goes green:
#1 Not Enough Chlorine
Chlorine is important for sanitizing water from bacteria and other contaminants. Lack of chlorine is one of the most common causes of green pools. If the pool water is not balanced with proper chlorine levels, algae will start to grow, causing the water to turn green. The growth of algae also speeds up as warmer weather arrives so a regular pool care routine can keep it in check.
#2 The Weather
Depending on where you live, the weather can have an impact on your pool water clarity. When pollen levels are high, the water may turn green more frequently. Pollen is too small to be properly managed by the pool filter and it might require cleaning with a brush or skimmer. For those who live in hot and humid climates where algae thrives, a higher amount of chlorine can help prevent potential algae buildup.
#3 Unbalanced pH
pH measures the acidity of your pool water, and can fluctuate due to weather, temperature, and pool use. If the pH of the water is too high, chlorine becomes less effective, which can allow algae to grow in the water. Monitoring your pH levels, along with a regular pool care routine, can help prevent an environment where algae can grow.
#4 Pool Pumps and Filters
If your pump or filter is too small for the size of your pool, the system can’t properly filter and get rid of algae and other debris that enter the pool. Or even the right size pump can’t effectively clear the water if it’s not running regularly. Check with your pool manufacturer for the right size and run time required for your pool to keep it safe.
Keeping an eye on your pool water conditions and equipment can prevent a cloudy green pool. pHin can help by reporting whether your pH levels need attention. It takes over 1,000 measurements a week,and will alert you through your smartphone app if your water’s pH is off. When there’s a problem, you’re not on your own – pHin also helps out by providing chemical dosing instructions to right the imbalance before the water gets off track.
