Mikro Basic - Eisenvolldünger (Fe Complete Fertiliser) adds the main micro-nutrients iron, manganese, copper, zinc, boron and molybdene. It is also rich in potassium and magnesium. The nutrients are stabilised in a variety of compounds thus remaining constantly available to aquarium plants.
Water changes of 25 to 50% per week are recommended to prevent a buiild-up of excessive micronutrients in the water.
| 10 ml Mikro Basic Eisenvolldünger (Fe Complete Fertiliser) per 100 l of aquarium water adds the following nutrients: |
| K | 1.0 mg/l |
| Mg | 0.4 mg/l |
| Fe | 0.1 mg/l |
| Mn | 0.0475 mg/l |
| Cu | 0.006 mg/l |
| B | 0.004 mg/l |
| Zn | 0.002 mg/l |
| Mo | 0.004 mg/l |
Aquariums can be supplied with the basic micro-nutrients either by Mikro Basic - Eisenvolldünger or by Mikro Spezial - Flowgrow.
Mikro Basic - Eisenvolldünger (Fe Complete Fertiliser) adds the micro-nutrients iron, manganese, zinc, boron, copper and molybdene and the macro-nutrients potassium and magnesium. This makes a lot of sense especially for a community tanks with high numbers of fish as you can be sure that all the necessary nutrients are added. At high stocking levels, the macro-nutrients nitrate and phosphate are brought into the tank by the fish. In tanks with a smaller number of fish, they have to be added by special fertilisers, like Makro Basic - NPK.
In Mikro Basic - Eisenvolldünger (Fe Complete Fertiliser), the nutrients have been stabilised by a number of strongly chelating compounds (EDTA, DTPA and HEEDTA), which keeps them available to plants for a long time. This complete iron fertiliser may hence be added once a week or daily.
| Dosage per 100 litres |
| Ample Light + CO2 | 2 ml per day |
| Little Light + CO2 | 1.5 ml per day |
| Without CO2 | 10 ml per week |
This fertiliser can also be used in tanks with shrimp and other invertebrates. Its very low copper content has been carefully stabilised and hence rendered absolutely harmless.
