AF Freshwater K Boost

Professional easily absorbable potassium fertiliser for aquatic plants.

AF K Boost fully replenishes potassium deficiencies, essential for aquatic plants. The plants quickly absorb the formula, so the effects are visible within a short time after application.

An important building block, potassium participates in many biochemical reactions, where it acts as an enzyme activator. Also responsible for osmotic regulation and transport of compounds in the plant. Potassium deficiency is characterised by yellowing of leaf edges and tips, progressing to necrosis in the later stages. 

Potassium concentration in the aquarium should be 10-20 mg/l. 

Supplementing should be continued until satisfactory results are achieved. Recommended parallel use with AF Micro, AF PO4 Boost, and AF N Boost. Absorbents such as zeolite and/or carbon may reduce effectiveness of the formula.

1 ml in 10 l of aquarium water will raise levels:
