So far, lighting is the most confusing thing I've run into :help:
The question is:
is it best to position a MH lamp so that it is lengthwise to the tank or crosswise to the tank? (when looking down from top)
For example:
Position #1, lengthwise:
[hr]
- - <--- Tank
- ooooo <-- bulb -
- -
[hr]
or
Position #2, crosswise:
[hr]
- o - <--- Tank
- o <-- bulb -
- o -
[hr]
I read a report where someone measured all areas of the tank with a light meter and determined that the projection of light from a MH bulb was to the sides and that the maximum light entering the tank was with position #2.
Thoughts?
