For a low tech setup you could use seachem flourish comprehensive and API leaf zone once a week for the ferts and seachem excel daily for the carbon suppliment. Petsmart should have it all but you could find it a lot cheaper online. And yes they all go in the tank I reccomend at least an hour before the lights come on sp it is mixed in the water column well and ready to be used by the plants.
