that looks good! you're off to a great start there. the only thing i am going to recommend is at least 4ml of excel daily(until you get co2, hopefully...). with that fixture that close to the tank your hairgrass is going to be covered in algae in a couple of months. i would hate to see that happen.
oh, one more thing. do you plan on dosing any ferts?
What would Honey Badger do?
