#HOW MUCH MURIATIC ACID TO LOWER ALKALINITY MANUAL#

This equates to approximately 6 fluid ounces of acid/gallon of water - an uncommonly high concentration of acid. Note: Some injector manufacturers state that a maximum of 5 percent acid can be used.

Read the injector manual to get this information or call the manufacturer of the injector. Once you choose an acid to use, make sure your injector can handle the task. Citric acid is a weak organic acid and a solid, making it safer than the other three but it is much less effective, and therefore more expensive to use. Nitric acid is theoretically ideal because it adds nitrate nitrogen but it fumes and is highly oxidizing, making it very difficult to handle. However, we do not advocate adding more than 2.25 fluid ounces of this acid to 100 gallons of water, because of the amount of P one would add. For low amounts of alkalinity removal, phosphoric acid may be the acid of choice. In our experience, the most effective and widely used acid is sulfuric acid however, this is one of the most hazardous acids to use. Table 1 lists criteria for choosing the right acid for your situation: relative safety, neutralizing power, cost, and nutrient content. The acids commonly available to growers include phosphoric, sulfuric, nitric, and citric. Once the role of alkalinity is understood, the grower may consider the following practical step to control alkalinity using acids through an injector system. Acids have been and always will be an excellent tool for growers to exert better control of irrigation water alkalinity (mostly bicarbonates and carbonates) and growing media pH.
