Most sanitation and filtration systems do a fantastic job of maintaining water quality. But even with the best equipment, occasionally you may have to address water clarity. Here’s a cheat sheet of what to do when your water looks less than clear.
Clear Green Water
High copper or iron content: Add a solution that decreases minerals in the water.
Lack of sanitizer: Shock-treat and check and adjust sanitizer levels.
Chemical solids dissolved in water: Use a clarifying agent to help remove build-up of particles.
Imbalance of pH or total alkalinity levels: Test levels and adjust as needed using appropriate solutions.
Hard water: Use weekly treatment and drain/replace some water.
Dirty filter: Clean and/or replace filter.
Cloudy Green Water
Low alkalinity level: Use an agent that will raise the alkaline level in your spa.
Low sanitizer level: Shock-treat, then check and adjust sanitizer levels.
High iron or manganese content: Add a solution that decreases minerals in the water.
