Dive Into Success: 2024 Certified Pool Operator Practice Test – Make a Splash!

Green water that is transparent is usually due to algae. Algae are microscopic organisms that can make the water appear green when they are present in large numbers. Algae can thrive in warm, sunny conditions and can quickly multiply in pool water if the sanitizer levels are not properly maintained. Keeping the chlorine levels balanced and regularly shocking the pool can help prevent algae growth and keep the water clear. Copper ions in the water, iron particles, and organic debris can also cause water discoloration, but they do not typically result in transparent green water.
