what would you suggest then if im looking for the best and fastest growth I could get with my setup I currently have? id like to keep anubias, java fern, rotala, cabomba, crypts, ambulia, amazon sword, hair grass, micro sword crystal wort and so on, maybe not all at once but I sort of want a setup that can grow all of those good enough to look nice and not die away. Also is Daltons aquatic mix a good choice for a nutrient rich base layer substrate? I was tempted to buy that aquabasis plus stuff but its abit expensive and figured that Daltons aquatic mix should be good enough. I was thinking an inch or so layer of Daltons mix and capped off with and inch or so of black silica sand.
