I always test for nitrates weekly as I prefer keeping my tank at 10ppm. Unless you really start getting a lot of plants right now that test is sufficient. If you get any Swords or Crypts you will want to get some root tabs for substrate fertilizer as these plants are heavy root feeders. If you get Water sprite I would suggest getting Seachem's Flourish Comprehensive and use it weekly after your WC
. That would be about it for what your wanting to do right now.
