    Does the color of the PL light matter? How does a bluish one compare with the bright daylight one? For planted tank with high requirement for light (maybe like riccia), is the bluish one sufficient?

    Get the bright daylight one. There's science underneath it, but the daylight one will be your best bet.

    Thanks for all the replies ... one BIG problem that I have is the most of the terminologies (NO3, KH, Kevin, etc) used here are too chim for me and I don't have the patience to read those lengthy detail writeup explaining a certain concept.

    What happened was I have 4 PL lamps (2 x 24W, 2 x 36W) and one of the 24W ones is bluish in color while the rest are daylight. I am concerned if this will affect the growth of my plants, esp those directly under the bluish tube. Shd I change the bluish tube to a daylight one? Is this necessary?

    i guess for planted tanks, the bright white ones would be better

    daylight white is 6500K but some people prefer 8000K which I personally find too bright and bluish when new.
    why I don't do garden hybrids and aquarium strains: natural species is a history of Nature, while hybrids are just the whims of Man.
