SEACHEM FLOURISH POTASSIUM 500ML
Seachem Flourish Potassium 500mL is a highly concentrated potassium supplement for the natural freshwater planted aquarium, supplying 50,000 mg/L of potassium to support vigorous, healthy plant growth. Potassium is a vital nutrient that can become depleted in rapidly growing tanks or where source water has low mineral content, and when it runs short it can become the limiting factor that slows plant growth. Flourish Potassium is designed to prevent potassium depletion and help correct deficiency signs that often show up in older leaves, such as yellowing (chlorosis), browning/leaf death (necrosis), pinholes, and weak stems and roots.
Unlike potassium nitrate or potassium phosphate (which also add nitrogen or phosphorus), Flourish Potassium is derived from potassium sulfate, letting you increase potassium without affecting nitrogen or phosphorus levels—useful when you’re trying to control a specific NPK balance.
Key features
-
50,000 mg/L potassium concentration for planted aquariums.
-
Derived from potassium sulfate to raise K without adding nitrogen or phosphorus.
-
Helps prevent or correct potassium deficiency symptoms (older-leaf yellowing, necrosis, pinholes, weak stems/roots).
-
Ideal for fast-growth setups and low-mineral source water where K can be depleted.
Directions (label-style)
