Here's a link to a 30" version that has both MH and PC so you can cover a better range of light periods.

This has nothing to do with my Odyssea refugium

I have looked into the Odyssea MH set up, but I have read the 250 watt ballasts are crazy dangerous..... It either fries or smokes.... I don't want to come home one day with a fire !!
That why I am shining away from it....

On a side note, I myself would go with a 30" hood for good even light coverage unless you were planning on having a lower light region in the tank for organisms that would not do well in an intensely lit position. I have looked into this rather extensively and it seems that if you are planning on having a large variety of different organisms, ie: not dominated by SPS, having a lower light area is a good idea, to approximate the different zones of a reef better.

But here is the thing... A SunPod 20" vs 30" ... its the same thing.. with the MH bulb in the middle... It doesn't make a difference what the size of the hood..... Or if you are working with a MH Pendant... its the same thing isn't it??? Light is dispersed across the 30 inch tank no matter how long the fixture is... with only one MH bulb in the middle.... I understand as you get larger the fixture 36" and up... it has two MH bulbs or even 3 MH bulbs.... so from my research it seems like 30" or lower fixtures... its all the same.. you are paying the extra $$ for a better "fit"

Haha, I think those are some of the interesting rumors I was speaking of. (you know the kind, "my friends brother knows this guy who has a friend who had one of these"...lol)

There's a pretty huge thread on RC about these and for the most part people are happy. They don't find the ballast putting out the right power though and so some have replaced the ballast to get better PAR.

Given your thoughts about the 20" versus 30" fixtures...maybe this one might be good for you. I don't know much about these guys but I've seen them mentioned here before.

Yeah but everyone need to buy a new bulb and a ballast with the Odyssea. So basically it cost more than the sunpod 150 watts...even though the Odyssea is 250 watts....

There's also a 24" set-up that has t5ho to supplement the metal hallide.
Might give you slightly better coverage than a 20" fixture (primarily due to longer t5's).

Could just hang something like that above the tank?

Wow 711 buxs... that way out of my budget....

I am thinking of sticking with the 30 inch SunPod 150 watts....i can get it in the US for 250 usd shipped to my friend...then she bring it up for me...

As long as people say the 14K bulb shouldn't be yellow, I am fine... it also have the lunar lights for dust / dawn effect .....

Yep thats exactly it. A 20" and 30" fixture is just made to fit different tank dimensions and, barring differences in the reflector or ballast used, will produce the same light.

Today went to the LFS ... and picked up four small pieces of corals...

Aussie Acanthastrea (purple/red + green ones)
Frogspawn (Hard to describe the color, but it isn't the common green or brown ones I usually see in stores)
Elegance coral (Green color)
Red Mushrooms on a rock

I will take pictures of it when it opens up later in the day

So, how 'bout those pics?
