Aquaforest AF K Boost 250ml

Aquaforest AF K Boost 250ml

Aquaforest AF K Boost 250ml is a professional, easily absorbable potassium supplement for planted aquariums, formulated to replenish potassium deficiencies in aquatic plants. It suits aquarists who see their plants' leaves yellowing and want to prevent that decline from progressing to necrosis. Its quickly absorbing formula is designed to show visible effects within a short time of application.

Why Potassium Matters

Potassium is an important building block for many biochemical reactions in plants. It also plays a part in osmotic regulation and in transporting compounds around the plant. When potassium runs short, leaves begin to yellow and, left unchecked, the plant tissue eventually dies off (necrosis). AF K Boost is made to fully replenish these deficiencies.
