let there be light(ing)
I was just wondering that the different types of lights are all for. I got my 110gal set up yesterday and it came with flourescent tube holders powered by a VHO light balast, no clue what it does lol
1) whats the difference between the types of lights? flourescent, metal halide, VHO, that kinda thing
2)whats the difference in the K ratings? or regular vs Actinic?
3) what kinda light do i need for something as big and deep as a 110 tall freshwater tank? no plants for the moment, but i might get one or two of those really long ones that climb to the surface
thanks for filling me in you gurus you :D
