Trees like oaks, elms , palms and pines can create a lot of pollen blooms that can fall into your pool water. This may cause your pool to take on a yellow or greenish hue.
Yellow or mustard algae is a form of green algae that has become resistant to chlorine and other sanitizers (algaecides or enzymes). Unlike green algae that floats on top of water, yellow algae clings to surfaces, such as the walls, bottom of the pool, on other objects like pool lights, main drain, ladders, or tiles.
Special treatments must be used to eliminate it for good. It brushes away very easily, but returns very quickly !
There are several factors that can cause pool water to turn yellow, including:
1.High levels of metals: High levels of iron, copper, or manganese in the water can cause it to turn yellow or brown. This is often seen in older pools with metal pipes or fittings that have corroded over time.
2. Algae growth: If your pool water is not properly balanced or sanitized, algae can grow and cause the water to turn yellow or green. This is especially common in warm and humid climates.
3. High levels of dissolved solids: Over time, minerals and other dissolved solids can build up in pool water, causing it to turn yellow or cloudy.
4. Improper pH balance: If the pH levels of your pool water are too high or too low, it can cause the water to turn yellow or green (ideal level 7.2 - 7.6)
5. Improper use of chemicals: Overuse or improper use of certain chemicals, such as chlorine, can cause pool water to turn yellow.
It's important to test your pool water weekly and maintain proper chemical levels to prevent discoloration and other issues. If your pool water has turned yellow, please click on the button below to see how you can treat and prevent it by developing an appropriate treatment plan.
