Grow red plants!
Seriously, though, it's basically a matter of light and nutrients. You have to adjust those based on what you have. That part can be difficult.
Co2 makes things easier (and more complicated) but is not necessary. Soft water (Kh 2 or below/Gh 4-6) makes things a lot easier but is not necessary.
If you are looking for input, post Gh, Kh, nitrate readings from what ever water you use for water changes. Then again from your tank (of you have a tank up and running now).
As well as...
Lighting used, both intensity and duration on what sized tank.
Substrate used ( I know you said every but what does that mean to you?).
Any fertilizer used and dosing regimen (how much, how often). Co2 use?
Typical maintenance schedule.
Hopefully others will chime in.
