#536 Balanced Minerals Concentration in Water involved in biological uptake and growth rates in fresh waters.
Each water sample is tested for this Set of Parameters: Phosphate, Nitrate, Nitrite, Dissolved Metals (Combined Metals Cu+2, Co+2, Zn+2, Cd+2, Ni+2, etc.) and Iron +2, Alkalinity and pH.
(7 tests on each water sample).
Safe Fast Educational Fun.
Supporting tests for biological growth studies and experiments for science project. Water samples from lakes, creeks, ponds, rivers etc. are tested for minerals required for aquatic biological growth. Chemical testing both mg/L (or ppm) and microgm/L (or ppb)) only takes a few minutes per sample.
