4 x 54w T5's

[Ansphire]

Hey people I just bought this fixture for a 55g tank..

I just had a quick question.. Will this light work on a 90g?.

 

[jddaniel]

Yes it will also work on a 90g. You will need to get the correct bulb combination for the type of corals you plan to keep, but it will work.

 

[magnoliarichj]

a 90 is wider and i would add bulbs.

So to add on to the question how many T5 bulbs would be required for a 90gal just keeping LPS, Softies, zoa's, and such then?

 

[photobret]

You could probably get away with the fixture you have if its only for those corals. Bulb wise I would go for:

F2B:
Ati Blue Plus
UVL 75/25
Aquasun
Blue plus

The joy of T5's s that you can mix and match bulbs to your liking...

I only run 4 54s on my 90. It keeps shrooms, rics, polyps, and zoas just fine.
For bulbs I kept it simple with 3 14k aquablue + giesemann, and 1 actinic.

Sorry I didnt meen to hijack your thread by asking that. It was just that I was just getting ready to start my own thread with the same question. Im glad to hear that I can keep them under that lighting. But I was also wanting to put a few LPS's in there also I guess I will have to see how they are looking when I put them in and move up if they are not getting enough light.

keep in mind that individual reflectors will almpst double the output compared to a fixture with 1 large reflector.

I run 4X39 on a 40 breeder and it keeps SPS happy.

most people make the mistake of starting there coral off to high in the tank under t-5s. so keep them low and bring them up slowly

 

[mrbigshot]

ind reflectors are worth about 30% increase in light output.

a 4 bulb with reflectors is as good as a 5 bulb without, not an 8 bulb without (as double the output would be)

 

[SHOmuchFUN]

For LPS, yes.
For SPS, no.

not to say you are incorrect, but can you tell me whare you found that information? Everything that i have ever read has implied that individual reflectors will add much more than 30% more light.
