Finally got the water tests back. Some problem with the e-mail address...

Please help me interpret these! Do I need to do anything? I'm guessing my alkalinity is low. I have about 9.6 acre-ft of water. How much lime do I need?

  • pH 7.98
  • Electrical conductivity 0.219 ppm
  • Total dissolved solids 140 ppm
  • Carbonate (CO3-) 0 ppm
  • Bicarbonate (HCO3-) 87 ppm
  • Nitrate-N (NO3-N) 0.059 ppm
  • Sulfate(SO4 2-) 4.1 ppm
  • Chloride (Cl-) 20.4 ppm
  • Phosphate (PO4 3-) 0.02 ppm
  • Calcium (Ca2+) 22.5 ppm
  • Magnesium (Mg2+) 3.97 ppm
  • Potassium (K+) 2.19 ppm
  • Sodium (Na+) 11.9 ppm
  • Iron (Fe2+) 0.03 ppm
  • Manganese (Mn2+) 0.005 ppm
  • Copper (Cu2+) 0.005 ppm
  • Hardness 72.7 ppm
