True! This plant requires a lot of light, C02, and soft, slightly acidic water. Having slightly acidic is an important factor in keeping this plant orange and robust. When I kept this plant it began to lose it's lower leaves, and turn green(even though I had 3.1wpg). I began looking for info. and asking people on other forums, they told me that having acidic water is what causes this plant to stay orange. I had to give up it since, my water isn't soft/acidic enough for it's likings.. But lots of people say it grows like a weed for them! Good luck with it..
