General information

Essential macro-elements to sustain plant growth. At the same time Fertil+ will increase the buffer capacity of the water, preventing over-acidification otherwise known as acidosis. This product is nitrate and phosphate free. While the major macro-elements occur in sufficient quantities in natural waters, they are quickly depleted in the confines of the aquarium. These macro-elements need to be added on regular basis (weekly or even daily) to keep the plants in top shape. The recommended dose is 1ml per day per 100l or 1ml per week for every 10l. For best results, we strongly advise to use the product in combination with Giovanni’s Plant Nutrition Trace+.
