http://brs.li/BRS160_Week20 Today’s episode is our second of five where we really explore lighting in the reef tank, in this one we are going to focus on metal halide lighting. We will start with who halide lighting is ideal for, the general advantages and disadvantages of halide lighting, and then evaluate halide lighting based on the criteria we developed a couple weeks ago including some really cool tests we performed based on those criteria. We'll share the importance of selecting the right reflector and bulb types, discuss some hybrid options and finish with some common installs and tips. Similar to T5’s, halides are a proven technology absolutely cable of maintaining awesome coral health combined with that high contrast visual appeal and shimmer everyone loves. Today’s halide users are those that only care about one thing: and that’s results. The number one advantage halides have is the longest track record of success. If maintaining a successful reef tank full of heathy corals is the only concern you can probably stop looking because halides are one of the best options and a staple in reefing for longer than most of us have even been in the hobby. The halide bulbs can produce both highly intense lighting with high PAR ratings as well as highly diffused light or even a hybrid of both all depending on the type of reflector and bulb used. The result is typically a really high contrast tank with plenty of light coverage but also a sense of depth that comes with some slightly darker areas in the tank. Halides are also considered to produce the best shimmer lines in the tank which gives that sense of movement that makes the tank look like an actual section of the reef rather than just a picture of one. The shimmer is also very natural looking and doesn't produce a "disco ball" effect.

Im having a optiwhite reeftank 24x16x16 with LPS and softies. I bought a maxspect 120w and just going with 45% white and 50% blues for 8 hours and my lps wont grow. Should i i increase the power to almost 100% white and 100% blues for some hours? Thanks for replys
In my country [Mexico] I cant find good light for reefing, besides I don't have too much money. Do yo think if I can get to work a 20W blue LED and another 20W red LED [for my mangroves] will work? my tank is 80 gal. and is empty.

You guys rock thanks!
The throw of the lamp should be along the length of the tank, not thrown out the front of the tank.
The ends of the lamps should point toward the viewer, not along the length of the tank as the lamps throw dictates.
I just run a hood that can be rotated to the correct orientation to make the most of the throw.
The reflective surface within the hood breaks down fairly quickly, too, and the hoods probably should be replaced on a regular basis...in horticulture they aim for biannual replacement, but that would really get expensive for most reef hobbyists, I'd reckon, though cheap and good hoods cost about as much as the lamp, though they are a bit ugly, if you need them out in the open and in view.
Some of these reflectors also defy what we think we know about the topic. The Bimini is one of them. This reflector produces a clear rectangular shaped pattern turned what most reefers would say is the wrong direction. If it was turned "correctly" it would perform poorly in a standard elongated rectangular shaped tank.
Our goal is just to produce the data and hope that reefers can use to achieve the best results for their particular situation. This is one of the reasons we selected a 30" inch cube which goes beyond the boarders of the shortest dimension of all the most popular tanks.
Not blaming you guys, but those lamps are poorly designed and will not provide optimum results...the solution is simple...rotate the lamp ninety degrees.
I will also say some of the reflectors defied what you might think in this regard. Dig into the results, particularly the Bimini.
