First, research research research. Use the sticky at the top of this forum for great info and ask alot of questions (started this one already..lol).
If I were you, I would buy a light that would get you at or close to 4 wpg
, I've heard to go with Compact Fluorescent Lighting Kits
or current or coralife or TEK if you can afford it.
Then get yourself some black seachem flourite as substrate. Around 3" deep or so.
Next you need yourself a 5 or 10 lb pressurized CO2cannister w/ a regulator, solenoid, needle valve and bubble counter. YOu also need a reactor, either a DIY or one you can buy.
After that go buy some ferts, there is a good link somewhere around here.
Then get plants, and plant em! Go with higher light plants since they'll enjoy the light and take off. Get that CO2
up to around 30 ppm
and then fight algea for a few months until you get the hang of things.
And then...and only after you've done all of this...probably years, possibly decades and maybe never, you can sit back and relax and enjoy your algea-free beatiful planted tank.
