loss of alkalinity from the sediment to the overlying water was found to be as large as the combined measured acidity input from the watershed and from direct precipitation to the lake, thus showing the significant role of sediment–water interactions in the alkalinity balance of some acid lakes....

Four rates of ground litter samples were incubated with an acid soil and after eight weeks soil pH and extractable cations were determined. The pH was strongly influenced by the addition of litter, and the increase in pH was linearly related to the amount of ash alkalinity added. Extractable ...
A spreadsheet was designed to offer a quick and practical method for calculating: 1) amount of nitric, phosphoric, and sulfuric acid required to achieve an endpoint alkalinity or pH in irrigation water; 2) the amount of nutrients added by the acid addition; and 3) acid costs. It calculates...
This should be enough muriatic acid to bring your alkalinity down to normal. In general, 20 ounces of acid will lower the alkalinity in a 10,000 gallon by 10 ppm.But what happens if your pH drops too low after adding muriatic acid? If you need to nudge your pH upward, you can run ...
