Another one of those dictums so prevalent in the pond world that is only partially true.parasites are now showing up with salt resistance.
Phosphorus does not present a health problem for humans unless the level is extremely high. Municipalities generally strive to keep this level less than 1.0 mg/L as any level over this will interfere with the operations of Waste Water Treatment plants.My tap water test at 2.0 ppm Phosphate. Is this a level of concern for human consumption?
I did a battery of test and became concerned when my holding pond rested at 2.0 ppm, the source of the phosphate however is the tap water.
The latest data for my city from 2015 says it is testing at .08 ppm.
