Just keep low to moderate light tolerant plants and you'll be good. Dose with Flourish Comprehensive and Excel as directed and you'll have a nice low tech planted tank.
Oh my, I just realized in that post I said I liked the Ecoxotic because it has mercury. LOL. I meant to say, because I don't
think it has mercury.
