Hi folks I got some questions on cfl n reflectors. Hope to learn
from your experiences. I'm cosidering adding this cfl to my existing
screen cus at this time of the year there is not much sun.

Q. Would a cfl 15w 2700 k be sufficient, or must it be a 23w 2,700k?
Cus I have the latter in another tank n it seems like blinding bright.
N it burned a hole in the algae of my existing screen too, though its
somewhat recovering now.

Q. My current screen is 18inch across x 12 inch height ,1 sided sun
powered, how many bulbs would suffice? Wattage?

Q. Reflector size n depth please ? Is the depth of the reflector impt?

Thanks for your input
