CO2 for planted tank
Need advise. Is CO2 really a necessity to keep the plants healthy? Not sure if the organic carbon thingy is available here in phils. Anyways, I currently have 3 plants (amazon, one with like the pines :), the other one a red one) - sorry don't know the names, and am planning to put in 3 more in the background, 3 in mid, and a few hairgrass in front, all in a 15g.
I saw some diy CO2, and was wondering if I really need all that. Will of course do this after the tank has cycled, and will of course get those Ph testers.
