Pink hue lights are great for planted tanks as they provide the red end of the light spectrum which is not essential but important(also makes your fish look good). Your supersun tube is probably a white tube about 6000 kelvin. Java fern is a slow growing plant (even with co2) and will take a while to settle in and attach its self to what ever it is on. Twisted val likes high lighting so it should do better with these new bulbs.
