The main nutrients nitrogen, phosphorus, and potassium are very important for the healthy growth of aquatic plants.

While these substances are sufficiently available in aquariums with many fish through their waste and uneaten food, there is often a lack of availability of major nutrients in plant aquariums with few or no animals. This leads to poor plant growth.

The product Sera Florena 4 is developed to nourish aquatic plants in aquascaped and Dutch-style aquariums with nitrogen, phosphorus, and potassium in ideal ratios - for healthy and vigorously growing plants. Sera Florena 4 is well tolerated by all invertebrates.

Recommended dosage: 

1 – 5 ml of Sera Florena 4 (depending on plant density) per 5.3 US gallons (20 liters) of aquarium water daily or as needed.
