CaribSea Super Naturals Midnight River 5lb
Midnight River is a dramatic all natural black substrate with a grain size in the coarse sand/fine gravel range (1-5 mm). The grain size and smoothness of Midnight River make it ideal for not only planted aquaria, but bottom dwelling fish such as corys and loaches. And as all the Super Natural Aquascapes substrates, Midnight River comes with a free bacteria packet perfectly dosed for corresponding aquarium size.
