PH Down are tank controllers that assist in reaching the desired pH level. The pH scale measures how acidic or basic (alkaline) a substance
is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic (alkaline).
Plants thrive in a pH range of 5.7-6.2. When preparing nutrients, or regularly monitoring your reservoir or tank, you should always check
your pH levels to ensure that the pH stays within an acceptable range for your plants. When pH levels become too high, nutrients become
non-bioavailable, a phenomenon commonly referred to as ‘nutrient lockout’. Accordingly, pH control using pH Up & pH Down is essential to
ensure that nutrients remain readily available for plant growth.
