Just worry about PAR. Truth is the corals adapt to whatever light they get. You can have the same species 5 feet below the surface and 25 feet below the surface in the same area. They will see a big difference in the light reaching them

I just received and hung my new ATI Sunpower fixture today. I want to make sure I install the bulbs correctly. In the User's Manual that accompanied the fixture, it says: "Each bulb should be oriented so that the stamp/label on the bulb is over the hole in the fixture." I'm pretty sure this means facing down, as into the water, but I want to be certain I'm installing them correctly. Also, does it matter if the label end is on the fan end of the fixture or not?

Thank you Ryan. I put the labels under the fan end, I'll switch them.

Let me explain the cooling system. The fans draw in cool air. That air travels over the ballasts and to the cord side of the fixture. There are vent holes on the cord side inside the fixture. The fresh cool air then cools the cold spot of the bulb. The air hits the acrlyic shield and travels down the length of the bulb and out the side of the fixture.

just mount the label end of the lamps so they are at the same end as the holes in the reflectors, they are easy to see

Can you have too much light over your tank when using t5's? I'm using the 12 bulb aquatic life fixture (2 sets of 6 36" bulbs) over my 125 and have heard it may be too much light?
Opinions? |

However what is actualy too much light is made up of many variables with the biggest being what actual corals you are tryng to keep. Most SPS are high light demanding corals and they more often fail because of inadequate light more so than excessive. In your case you might have 12 bulbs but you also have a 125 gallon tank. Your bulbs are 39 watts each so you have a total of 468 Watts of light or about 3.7 Watts per gallon. I'm only using slightly less wattage on my 120 gallon at about 3.6 Watts per gallon. I have seen people going as high as 4.5 Watts per gallon without a problem with HO T-5's. The secret is in the selection and placement of your corals. If you any corals that do not like a lot of light then simply put them low or in shaded areas. The corals that like a lot of light can be best placed high near the light bulbs.

Watts per gallon does NOT matter. Please forget that rule.
The fixture and bulbs used make all the difference in the world! On my 40 gallon breeder I was running about 2 watts per gallon and had to shade my LPS or I would fry them. I even had to keep some SPS on the bottom or they would get mad. So as you can see, watts per gallon is useless. 3w per gallon from an ATI fixture is TOTALLY different than 3w per gallon from a Current USA fixture. The ATI will have almost double the light output and yet, watts per gallon is still the same. With an AquaticLife fixture on a 125, you don't have too much light.

I am just starting to setup a 90 gallon reef. I am looking at all the lighting options out there....MH, T-5, LED'S. I am really leaning towards T-5's just due to the fact of heat and power consumption. I'm not really sold on LED's yet. I would like your opinions on and suggestions on fixtures. 10 bulb setup or 8. I am planning on having an assortment of corals, not just sps or lps. We can hold off on the bulb configuration for the moment.

8 or 10 bulbs is too much on an 18" wide tank.

I never said it did. I only used a comparison where these light combinations were in similar ranges.

This is where doing some research on what is out there, how it works, and why one design is better than another really pays off. Very often there are applications where a $400 light fixture would be a waist when there is one for $200 that would do a better job. While in another application the difference between a $380 and a $400 light fixture is worth many times the added $20.00 expense.

Vic
What color temp were the Iwasakis bulbs you were using? Are these are the 6,500K bulbs that are generally rated as the highest PAR for Metal Hides? If so than you relay want to shift your color spectrum away from the blues or drastically increase your light in order to trick your eye. If you could tell us what bulbs your presently using we could give you some ideas. This is one of the cases that I always emphasize where personal taste is an important contributing factor to bulb choice. To duplicate the MH 6,500K Bulbs the GE 6,500K HO T-5 bulbs are probably the closest thing out there. But if your looking at color and growth from your coral these bulbs create to much red and yellow and not enough blue. I know when I first switched from MH's to HO-T-5 I loved the look of 4 420nm atinics on dawn to dusk and 4 10,000K bulbs on my Midday cycle. To me it seemed brighter and gave a crisper white than than my old 6,500K MH's. Through the years of trying various other bulbs I have found that a more blue spectrum is what I like now. To me the 6,500K bulbs simply look too Yellow for my eye. Not knowing where you at the start with your HO-T-5's I can only make a suggestion that you switch one bulb at a time to something like the 6,500 K bulb until you get the brightness and color spectrum you like. Other bulbs you can consider for brighten things up are the KZ New Generation, or the KZ Coral Light 10,000K. But only change one bulb at a time and give your eye at least a week to adjust to the new lighting before you make another change.
