Product Overview
Iron deficiency is the most common nutrient problem in aquaponics systems and shows up as yellowing leaves with green veins (interveinal chlorosis). Fe-DTPA chelated iron remains available to plants at the near-neutral pH levels used in aquaponics (unlike standard iron which locks out above pH 6.5). This 500g bag makes a concentrated stock solution — add at 2–3g per 1000L of system water when deficiency symptoms appear or every 4–6 weeks as prevention. Safe for fish and beneficial bacteria at recommended rates.
