hi guys sorry to keep asking questions

the reason for this post is i was wondering what type of fluorescent tube lighting you guys generally use, now after reading the care sheet by john (excellent btw), i was unsure if mine is good enough. at the mo i use a hagen 18", 15w sun-glo bulb, i understand this won't allow for d3, but the cricket feed i use already has this in.

so this leads me to mt next question, the supplement i use, is it ok, or do i still need to dust (pics and more info can be given)

all in all is my light ok, and my little guys in take of d3

cheers tone
