fuentes925 Posted July 24, 2003 Share Posted July 24, 2003 Hi I bought a established nano and it only has about 1" of LS. The sand it currently has is a large grain sand which looks like ground coral rubble and some ground shells. I am going to be adding a fuge and more sand and rock to the main tank. What is the best grain size for a DSB? Would it be good to mix my large grain with a fine sand? What about South down, Agronite? Fuentes925 Link to comment
