Big Pine Chlorophyll and Phosphorus Testing

Chlorophyll is a measure of algae and organic matter. Lab testing tells us these levels. This is a primary factor that people observe as the quality of the lake.

Phosphorous is the measure of the amount of nutrients in the water. This influences plant and algae growth. Lab results are trended over time. Human use can impact these trends. Keep your septic in order, don’t use fertilizers and be aware of your prop wash stirring the sediment.
