PRODUCT OF NETHERLANDS Essential macronutrients Easy-Life Nitro and Easy-Life Fosfo are used to compensate for a deficiency of nitrogen (N) and phosphorus (P), respectively. A deficiency of these macronutrients immediately leads to faltering growth or even to growth arrest. A shortage of N and P can quickly arise in plant aquaria that contain very few fish or no fish at all, because very little or no fish feed is used. Together with fish excrement, fish feed is the most important source of N and P. A deficiency can also arise in aquaria with a very high density of plants. Nitro (which contains nitrate NO3) and Fosfo (which contains phosphate PO4) immediately compensate for these deficiencies. The Redfield ratio is usually used to decide on the correct ratio between nitrate (NO3) and phosphate (PO4). See further on for a detailed explanation. DIRECTION Add weekly after measurement 10 ml per 500 liters increases the NO3 concentration by 2.0 mg/l (= 2 ppm) and the K (Potassium) concentration by 1.3 mg/l (= 1.3 ppm) Extra nitrate is mainly added in planted aquariums with many plants and few fish. In such cases there may be a shortage of nitrate that causes plants to grow poorly. Normally the target value of NO3 is between 10 - 20 mg/l (= 10-20 ppm).
