Makro Basic - Phosphat ads the essential macro-nutrient phosphate to your aquarium water. Phosphate is the trigger for water plant growth and can be added specifically for increasing the growth rates of your plants. A decreased dosage of phosphate will help you limit these growth rates.
Weekly water changes of 25% to 50% are recommended. The dosage can be raised or reduced depending on your requirements. If your tank water shows high readings of phosphate from the start, this fertiliser is not suitable for your aquarium. It has been designed to prevent the accumulation of large concentrations of macro-nutrients. If high levels of nitrate occur, please reduce the dosage.
| 1 ml Makro Basic - Phosphat per 50 litres of tank water adds the following nutrients: |
| PO4 | 0.1 mg/l |
| K | 0.04 mg/l |
The basic supply of macro-nutrients in a tank is provided either by our NPK fertiliser, our Estimative Index fertiliser or by our single-nutrient fertilisers Makro Basic - Nitrat, - Phosphat and - Kalium (potassium). Our aquatic plant fertiliser Aqua Rebell Makro Basic - Phosphat is a very important component in our single-nutrient fertilising system. It adds the essential nutrient phosphate to the aquarium and is also optimally suited for batch fertilisation (larger fertiliser quantity given just once), preferably after a waterchange. Aqua Rebell Makro Basic - Phosphat can of course be dosed daily, too. Phosphate is of utmost importance for healthy plant growth.
| Dosage per 100 litres |
| Ample light + CO2 | 1 ml per day |
| Little light + CO2 | 0.5 ml per day |
| Without CO2 | 1-2 ml per week |
This dosage suggestion is just a guideline. The dosage may have to be raised or lowered depending on the conditions in your tank in order to give you good results.
