Brightwell Aquatics Florin K – Concentrated Potassium Source For All Planted Aquariums, 500 Ml

Brightwell Aquatics Florin-K is a high-purity potassium supplement and is free of chloride (while chloride is a vital element to plants it is required in a very small concentration provided in Brightwell Aquatics FlorinMulti). Because the potassium requirement of aquatic plants is high relative to that of other nutrients Florin-K is very strong (50000 ppm) making it an effective and economical potassium source.
