you can take those plants and on the right and left side you can use the to make it kinda like a jungle and then take some swords or ancharis to cover all along the back and infront of that put the wood and for a foreground you can use dwarf hairgrass and ot will look pretty natural and you dont need yo use all the rock and wood also you can sell some of those plants and replace them with something else and for co2 can can have a diy co2
