OK. Here's the thing. You do not need CO2 or any fancy lighting to have a planted tank. You see, CO2 and that are for High tech tank, which lots of light, lots of fertilizers... And a lot of difficulty math. To have a basic planted tank, all you need is 1
WPG of light. Sure, you can only grow a few kinds of plant but it works and you can get some brilliant results. You won't need to do much, just you water changes. You might want to invest in a special planted tank substrate mind! Vals, Crypts, Amazon sword, Hygro, Java fern, Africa fern, Moss, Dwarf hairgrass, Anacharis , Anubias and Hornwort can be grown with ease like this!
Abut
aquascaping. You want to start with the centerpiece. That's easy, put it in the middle! Not. Say that this is a Planted tank:
OOOOO
I will highlight in red the good places to put a centrepiece:
OOOOO
Only put one centrepiece in the tank! Remember, the centrepiece must be an eye catching specimen, Anubias and red plants are good. Try Echindorus 'Ozelot'.
Then, think about hardscape. Try a long branch of
driftwood to move your eyes around the tank! It's good to have something like this 'errupting' from the centrepiece plant, and guiding your eyes to the secondary centrepiece. Try and incorporate lots of movement into the tank like that as your eyes will feel guided around the tank.
