GreenWorks Potassium Sulfate fertilizer (K2SO4) - 200g.

If the water used for water exchange does not contain enough Potassium (K), the addition of Potassium Nitrate (KNO3) and Potassium Phosphate (KH2PO4) usually does not introduce enough of this macro-nutrient into the water. In such cases, Potassium Sulphate (K2SO4) should be added. Dosage based on the Estimated Index (EI) method developed by Tom Barr. The description of the method in Hungarian can be found here, and a complex excel calculator to help calculate the dosage can be found here. By adding the right amounts of the ingredients, the symptoms of plant malnutrition and the associated algae growth can be practically ruled out (!). (Note: algae growth is not only caused by a lack of plant nutrients.) For those who are averse to "chemistry," we recommend the Green Aqua liquid plant formula composed of dry plant foods. Potassium Sulfate (K2SO4) is supplied in a resealable plastic box that protects the powder from moisture and other damage.

In addition to CO2, we need to add phosphate, potassium, nitrate and trace elements to the aquarium to meet the nutrient needs of aquatic plants. These can be delivered with the following plant nutrients:

• Potassium Nitrate (KNO3)
• Potassium Phosphate (KH2PO4)
• Potassium Sulphate (K2SO4)
• Chelated Trace Elements (Fe, Mn, Cu, Zn, B, Mo)

The Green Aqua Micro ingredient contains the best and most stable HEDDTA chelates on the market!

In the absence of proper chelates, the chemical bonds of the trace element (micro-nutrient) are easily broken down and the plants will not be able to absorb the nutrients properly.
