Man I would really like to get some live plants in the tank. I was actually researching last week what I could get but I assumed my lighting was not sufficient. Also the more I researched the more "complicated" it seemed (special substrate, co2 injection, fertilizer, etc.).
I'll look into these for sure - thanks.
Check my tank in my profile.
Marineland double bright, seachem's flourish once a week if I remember, a root tab for the sword. I have tried a large variety of plants and only the most light needy don't do well.
That's about as complicated as it gets. You don't need CO2 unless you are really cranking out the light intensity, special substrate is marginally a benefit, depending on which one, not a benefit at all. Fertilizer... solid ferts can be a benefit but in a lower light low tech setup not really needed. Your tank is already cycled so you aren't worried about having enough to replace the cycle.... great time to play if you are considering it.
Get some crypts, sink them in the substrate and see how they do.
