Aquarium Advice Regular
I added purple cabomba and another thick-leaved stem plant that I forget the name of to my tank a month or so ago after my stand debacle. They are growing well, but all new growth is noticably yellower than the lower sections. I have always thought my tank had more of a yellow tint than I wanted, but figured it was because of the tannins in the water and the 6700K bulbs producing a 'yellower' light than I expected, or just because of the off white wall behind the tank. Watching new plants start to yellow, especially the deep green purple cabomba, has opened my eyes.
I have about 50/50 flourite/gravel mix as a substrate, and 2.7 wpg PC lighting. My pH is a perfect 7.0 and nitrAtes are ~10-20 ppm. I need to get a phosphate test, I know.
I'm planning on setting up a pressurized CO2 system in the near future, but I would have thought the growth would have stunted if that was the problem.
I want deep green plants. What's holding me back?
