Black Water Expert

Simulates Conditions found in Tropical Freshwaters

KENT MARINE BLACK WATER EXPERT contains natural humic and tannic acids that simulate water conditions found in the Amazon region of South America, Southeast Asia and Western Africa. Excellent for Discus, Tetras, Angelfish, Barbs, Gouramis and all other soft water fish. Encourages spawning and aids in the hatching process.


Shake well before using. Add 5 ml (1 tsp) per 10 gallons of aquarium water every week and after every water change. For breeding, or when using very hard water use 10 ml (2 tsp) per 10 gallons of aquarium water every week.

KENT Marine Black Water Expert will turn aquarium water a yellow or light brownish color. It is recommended to suspend carbon and resin filtration during use, as they may reduce product benefits. Designed to use in aquariums with live plants.

When using live plants use KENT Marine Pro-Plant and KENT Marine Iron & Manganese to provide the additional minerals and fertilizers live plants require.

KENT Marine Black Water Expert should be used simultaneously with KENT Marine Discus Essential to provide needed trace minerals to freshwater aquariums.
