The Ista black water extract contains essential trace elements, vitamins and extracts of peat, tropical roots, bark and wood originated from tropical rainforests.

Using black water extract can help to stimulate the natural colour of fish, improve fish breeding and spawning rate, and increase resistance against diseases. Black water extract also helps to reduce the pH value and hardness of the water, creating slightly acid and softer water, effectively reconstructing a soft water environment found in the wild.

Black water extract provides ideal conditions for keeping discus, angelfish, neons, barbs and gouramis. Available in 6 different sizes.
