an update of my aquarium, now with black gravel (=
CaribSea Arag-Alive Hawaiian Black Aquarium Gravel | Petco
Flourite® Black is a specially fracted stable porous clay gravel for the natural planted aquarium. Its appearance is best suited to planted aquaria, but may be used in any freshwater aquarium environment. Flourite® Black is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as laterite are not necessary. Flourite® Black is not chemically coated or treated and will not alter the pH of the water. Flourite® Black is good for the life of the aquarium and need not be replaced. I haven’t had much luck with plants but I still use gravel. I like how the black makes the fish look & I have a black background too. I found some big rocks on the beach that look nice in there and the fish hid around them. I’ll be buying a new cylinder aquarium soon and this post is a good guide for setting it up from step one.
