| Safe Use of Acid Checklist | |
 |
ALWAYS ADD ACID TO WATER, NOT WATER TO ACID! |
|
Selection of which acid type to use should be based on the nutrient program being used, type of equipment available and degree of safety desired. All acids pose a health threat if they come in contact with skin. Relatively speaking, phosphoric is the safest, followed by sulfuric and finally nitric acid. |
|
Use caution when working with acids. Always wear proper face, hand and body protection. |
|
The acid must be injected with a separate injector or a twin headed injector. It should not be added to the fertilizer concentrate. The acids in the concentrated form can corrode metal pipes. |
|
Retest your irrigation water (at hose end) after starting acid injection and 3-4 weeks later to confirm the adjusted pH and alkalinity values. Sometimes higher pH's will result in the first week of acid additions because the acids tend to dissolve the built-up hard water deposits in pipes. |
