New thinking teaches us that nitrates and phosphates are not the cause of algae formation. It is the lack of these macronutrients that leads to the formation of algae, again due to the leakage of sugar from the plant. Of course, a very high phosphate content (> 2.0 mg / l) creates problems with algae, but a value of 0.5-2.0 mg / l PO4 is acceptable and does not cause algae formation. Typically, the plant is supplied with nitrogen and phosphorous acid when fed with fish or waste. However, with a small amount of fish, a poor diet, or a large amount of plants and light, it is precisely these macronutrients that may be deficient. Many people channel their NO3-PO4 content through the Redfield factor to neutralize the deficiency. The Redfield Ratio is a C-N-P ratio of 105-16: 1. In practice, we use the ratio between N and P (16: 1) and convert that to roughly nitrate and phosphate water values. With the addition of additional nitrates (Easy Life Nitro) and phosphates (Easy Life Fosfo), the correct ratio can be achieved and deficiencies prevented.
Easy-Life Nitro dosage:
10 ml per 500 liters increases PO4 concentration by 0.1 mg per liter.
