hey guys, justw ondering if anyone has any links to good sites with info on lighting systems. i'm just looking for explanations on what all the equipment is and does that i need and what you need for what and so on and so forth. just trying to get a grasp on hoods and ballasts and the different bulbs. kind of confusing because i have never seen any of the stuff in real life, just heard about it on here. thanks
Figuring out how to keep my fish healthy is like the pethagorean theorem; there is no solution.
