Support healthy, vigorous aquatic plant growth with Seachem Flourish Potassium, a concentrated potassium supplement designed for freshwater planted aquariums. Potassium is an essential macronutrient that supports photosynthesis, enzyme activity and the movement of nutrients within plants. In planted aquariums, potassium can become depleted over time, particularly in densely planted setups with fast-growing aquatic plants.
Flourish Potassium helps replenish potassium levels without significantly affecting general hardness (GH), making it a useful addition to a balanced aquarium fertilisation routine.
Essential plant macronutrient: Supplies potassium required for healthy aquatic plant development.
Supports vigorous growth: Helps maintain normal plant functions and healthy foliage.
Helps prevent potassium deficiency: Supports plants showing signs such as yellowing, pinholes or damaged older leaves.
Ideal for planted aquariums: Suitable for low-tech and high-tech aquascaping setups.
Does not significantly increase GH: Allows potassium supplementation without substantially increasing general hardness.
Suitable for demanding aquascapes: Helps replenish potassium consumed by fast-growing and densely planted tanks.
Complements other fertilisers: Can be used alongside Seachem Flourish and other nutrient supplements as part of a balanced fertilisation programme.
Standard dosage: Add 5mL per 125L of aquarium water.
This dose increases potassium concentration by approximately 2mg/L.
Dose as required based on plant growth, potassium availability and aquarium conditions.
For smaller aquariums, measure carefully using an appropriate dosing syringe.
Monitor plant health and adjust supplementation to avoid unnecessary dosing.
