Dennerle Plants Liquid fertilizer contains iron (Fe), potassium (K) and trace elements, and is designed for aquariums with few plants and/or many fish. It can be termed a complete iron supplement. This fertilizer is lacking nitrate (N) and phosphate (P), nutrients which are usually provided by the fish population, so do not require supplementing. Iron, magnesium and other crucial micro-nutrients enable robust, green plant growth. Liquid fertilizer is safe for use with invertebrates, such as shrimps, crayfish and snails.
