I would strongly suggest an Aquactinics Constellation as a compromise between the two. Looks better than both IMHO and will have better output than the Tek even with the external fan running PLUS it also has a splash shield so you can sit it right on the tank if you wish which gives you a nice gain in the amount of light reaching the bottom of the tank.

OK Grim, it's gonna be the constellation 7 bulb for my 48x24x20h tank. i'd like to know what bulb combo to get lighting like szymon tank. He has a 10 bulb setup so I'm not sure which to drop off and which to add. Do you think the combo will also encourage growth? here's a pic of his tank for ref.

I've got some pink and purple birds nest, and some red planet that are pretty much brown. Showing good growth, but I'm not thrilled with the color.
This is what I have so far. Can someone recommend something that might help?

Get a UVL 75/25 and try it in place of Aquablue. It has some red output and should pop your reds, pinks and purples better. Fiji Purple would work too.

Just cool the lamp ends. I never experimented enough with the 80 watt set to see how easy they are over cooled but the standard T5's will lose output with even a moderate amount of air directed at the center of the tube.
Thanks for the suggestion. It is indeed a very beautiful fixture with a nice price middle ground between those other two. At 14" wide it should fit perfectly over a 120 oceanic tech (24" front wide with euro bracing).<a href=showthread.php?s=&postid=15001537#post15001537 target=_blank>Originally posted</a> by The Grim Reefer
If you could see the fixtures side by side I think you would understand the price difference. The ATI is better engineered and has a lot better output due to the cooling and superior reflector materials and design but you can add an external fan on the back of the tank blowing across the rear of the Tek at the center of the fixture and score a nice gain in PAR, just make sure you don't use the splash shield and mount the fixture at least 4" above the water.
It still wont match the ATI performance or look but it will do well.

on another note, what is your thoughts on using (2) 48" 8 bulb tek light fixtures to light a 96x24x24 aquarium that is sps and clam dominated?

Grim I have a specific question for you. Will a Blue 450/460nm 20k bulb provide as much PAR as a 20k daylight bulb and still get sufficient growth? And secondly if I were to only run 2 "daylight" bulbs on my 8 bulb fixture and a combination of blue bulbs and antinic bulbs would that be enough daylight bulbs to achieve maximum growth?

What would the minimum number of bulbs needed to keep any type of SPS and clams on the substrate in a 40 breeder? I know it depends on the fixture and bulbs, but how many would you suggest on opposite ends of the price ranges.
1. ATI Powermodule fixtures
2. Nova Extreme Pro fixtures
Thanks

Grim,
I was heading down the retro fit path but having looked at the Constellation Series Aquactinics 48" 7 lamp T5 fixture I think that is an amazing unit. I like the 7 lamp with three different switches, excellent flexibility. If I were to use it in a well ventilated canopy or to reconfigure and create a open top canopy of sorts, do you have any specific advice having used this fixture? I know the fans are on the top, what are the smaller holes on the top? Would it make any sense to mount fans (e.g. 3" Icecaps) above the fixture in a canopy to ensure proper air flow if the top was not completely open? My initial vision was the fixture placed fairly close to the water in the canopy on rails so I could slide it forward or back in the canopy for maintenance with 3" Icecaps above the lighting unit bringing fresh air into the canopy from each side of the canopy. There would be an open section in the top of the canopy (call it 46" x 8") and the front lid would be an L shaped piece that flips back (I have this with PC lights right now) providing really nice access for maintenance and feeding by flipping it back and sliding the lighting unit back within the canopy. Any advice would be appreciated.
