FOR BEST RESULTS: Always use unchlorinated water, maintain and adjust pH levels between 5.5 and 7.0, and check reservoir after adding all nutrients. Oxygenate water before and during application. To prevent nutrient settling, always use a pump at the bottom of the reservoir to continually agitate and mix the nutrient water during application.
