Black water also helps lower the water pH as soft water has a strong tendency of pH instability.

RB Aquarium Series Superior Black Water

For my aquariums, I used before the Ocean Free Super Natural Black Water especially for my discus fish. The lights in my aquariums seem so bright and adding black water makes it dimmer which is good for fish. Right now, I am using R.B. Aquarium Series Superior Black Water.
