Hydroponic Filtration

Another aspect is the ph of the water water. Alkaline water contains high level of dissolved carbonates and bicarbonates of calcium and magnesium as ions. The alkalinity of water is the concentration of all sorts of ions in it, like calcium, magnesium, sodium, potassium and their carbonates and bicarbonates compounds. And bicarbonates are the worst offenders of the two. Alkalinity insidiously accumulates in your growing medium in a vicious cycle that will cause your growing medium pH to climb faster and give you pH stability problems in your reservoir and growing medium, substantially decreasing your yields.
