Dennerle Black Peat Extract 500ml

Dennerle Black Peat Extract is derived from natural sphagnum peat and delivers a concentrated dose of humic acids, fulvic acids, and tannins that replicate the chemical environment of tropical blackwater rivers and streams. Adding this product to the aquarium naturally lowers pH, reduces carbonate hardness, and tints the water a natural golden-brown color characteristic of blackwater biotopes. These conditions are ideal for tetras, wild bettas, apistogramma, discus, and other soft-acidic water species. The extract also has mild antibacterial properties that benefit fish skin and gill health. Dose gradually and monitor pH to avoid rapid changes.
