NATURE FERTILIZER by Oliver Knott: Special engineered plant fertilizer containing: Potassium, magnesium, iron, manganese, copper, zinc, boron and molybdenum. For use in plant aquariums where NATURE SOIL is used as bottom layer, and in tanks with a similar active bottom layer by other manufacturers.
How to use: Add 1 ml Nature fertilizer per 20litre water per week in a newly started tank. Double the dose to 1 ml per 10litres during the first 2-8 weeks as the biological balance is stabilising, and the plants start to grow. Depending on the speed of growth (light intensity, CO2 level, number of plants, plant species etc.), it may be necessary to add up to 3 ml per 10litres per week. (In extremely fast growing tanks even more).
Increase the dose if the new leaves turn out smaller and paler than the previous ones. The dosage should maximum be increased with 1 ml per 10litre per week.
