Fluval Edge Substrate
I am starting a new Fluval Edge, and I was wondering since i won't have any stem plants, mainly just moss and ferns. Do I really need to get a Substrate like Flourite?
Also, Im going to make this mainly a shrimp tank, do I really need to get a shrimp substrate?
and How much would I need? Would the 8.8 pounds of the Fluval Shrimp Substrate enough?
