Same intensity ?? Could you please expand on this?
I know the old watts per gallon adage has fallen out of favor but what is it, that "most important quality" I should be looking for from whatever type of light I get ? Intensity? penetration? what ? as it relates to a mixed tank of fish, low & high light requiring corals.
when referring to corals light needs most everyone refers to moderate and high? what do these mean? can you have High light from VHO
's and PC
's ? what would be moderate and high for each? or is High not attainable for these and only a virtue of MH
or $$$$$$$$ as I like to refer to them. If I'm getting the same intensity from 260 watts of PC
as 440watts of VHO
because they penetrate better, at what depth does this become a factor?
Where can I get some "good" information on this subject? I've done search upon search in this and other BB's and also searched the internet to really little avail. most of the recent posts(questions) on lighting are quickly shrugged off with a short sentence or a "do a search on lighting".
The more reading I do the more it seems to me that lighting a marine tank is Voodoo.....and it's painfully obvious that it's the one area that is being used as a huge $ maker for the retail industry at the moment. $175 for a ballast? come on.
Sorry for the rant...I've been reading about lighting every chance and in every place I can but everything I read contradicts everything else! the whole **** thing is driving me crazy......
Thanks for any and all input.
