Frag tank lighting... What's the best for growth?

[gobytron]

MAYBE in alberta sloatubes MIGHT work.
Calgary is the 2nd sunniest city in Canada.


even then, it's doubtful there is enough annual sun to make solatubes work for a reef aquarium....especially a frag tank.


Do a little research into it and you'll see that a significant number of solatube tanks actually need supplemental lighting.
