Welcome. A ray2 should be good for the hair grass. At 16" (with soil) it should provide about medium light. You can reduce intensity with egg crate or a semi opaque plastic if the light is too strong and u get algae. For carbon you can start with seachem excel. Plants need some source of it to grow. Ecocomplete is fine, there is also active flora which is similar but some ppl have seen better results.
