Sand/gravel for the Supershrimp?

[allisonnorberg]

Hello everyone! I am thinking about getting the Nat geo sand and gravel rocks that they sell at Petco for my shrimp tank. Has anyone used this brand and was it okay for the shrimp? I want to get the black sand and some of the “river rocks” they have. Thanks in advance

Any substrate should do. I am using the natgeo one myself. The tiny tiny black pebbles/sand. I have no issues.
