I wonder why they don't address Phosphorus and Nitrogen in ponds? If they don't test for SRP = Soluble Reactive Phosphorous this is what feeds plants and algae should not exceed 0.020 mg/L
According to 2 labs I called, the following terms are equivalent:
Soluble Reactive Phosphorous (SRP) = Orthophosphates = Free Reactive Phosphates.
My lab test reported Orthophosphate, so I think I got what I wanted in that category.
