Ask your pool dealer for the recommended procedure for total alkalinity adjustment. Your water test kit, or your dealer’s test will show a total alkalinity reading. Simply put, this is the ability of your pool water to counteract the changes in the pH level. Ideally, the total alkalinity level should be at 100-175 ppm.

This test measures the active soil acidity or alkalinity. A pH of 6.9 or less is acid. Soils with a pH of 7.0 are neutral; values higher than 7.0 are alkaline. Under normal conditions, most plants grow well when soil pH is in the range of 6.0 to 7.5. An application of lime should be considered for most non-legume crops when soil pH is 5.5 or less.

High levels of cyanuric acid require dumping 50% of the pool water and refilling to dilute cyanuric levels. STABILISER: (aka conditioner, cyanuric acid) A chemical which when added to a pool's water in the correct levels (25 to 60 mg/1) will reduce the loss of chlorine to the sun's ultra violet rays. The chemical is Isocyanuric acid.

To lower total alkalinity use muriatic acid or dry acid (pH minus). CALCIUM HARDNESS. Hardness: Hardness is related to Alkalinity. Hardness measures the amount of calcium, magnesium and manganese (which are three alkaline materials) that are present in the water. The ideal range for hardness runs from about 200 ppm to 400 ppm.
