What would you do? - Tank Lighting Upgrade.

5) keep the 4X54 T5s and add 2X 250W MH

That would be my choice

Getting everything to fit over your tank may become an issue. How wide (front to back) is your tank?

This what I would recommend also, make sure to get hqi (double ended bulbs) not moguls.

I ran one of the cheaper 4 bulb units over my 90g. Great for soft corals but not enough for sps. A pair of 250w halides I put over the same tank was no comparison for the sps corals. Like night and day and the corals showed the difference.

Now the high end t-5 fixtures may a different story but never owned one. If you like the t-5 look, then I like the idea of adding another 2 or 4 bulb fixture. Guess it depends on how many bulbs one wants to replace every year and the corals you wish to keep.

I've been doing this light thing (for FW High Tech planted) for a while and never really thought about this. Great point.

What type of corals do you see yourself keeping? LPS, zoas/palys, SPS, mixed reef?

If you go with 400W halides you never need to worry about "upgrading" again, and can keep any coral you like in terms of light. 2x250W would also work with florescent lights for actinic/dusk-dawn effect. I personally use single ended bulbs, lots of selection in terms of light spectrum and cost.

I actually have a 1X400W setup sitting around.. but I am a little concerned about heat with that light (especially a pair of these lights). I have a little bit of a vertical limitation and the light would be about 3"-4" off the water.

If I ran 2X250s.... couldn't I put SPS (eventually) half way up? I realize that coverage to the bottom wouldn't be great...

Keeping 400's that close to the water could be a concern, when most people put their tank in a wall they usually have a little more hight to work with (as everything is hidden). 250's would also present a similar challenge, although not as bad as the 400W's.

You could indded keep SPS half way up and higher with the 2 x 250W, but should the SPS bug hit (which has been known to happen!), well many people want to upgrade to the 400's.

My thoughts exactly.

There are small reflectors, the Sunlight Supply Reef Optix reflectors are pretty small. PFO too. I'm sure there are others I'm not thinking of. Oh, Hamilton. You can often just buy the reflective piece without the pretty outer casing, and that would save space as well. I can't seem to find a link to any of those though. Make sure you buy reflectors that are closed in the end, not just a half cylinder shape with open ends, they lose a lot of light.

Wow.. I didn't expect that many responses..

This is one of those questions that you "seasoned" reefers probably get over and over and over and over again..

What light should I get? What light should I get? What light should I get?

- rinse & repeat -

As for the "in-wall" clearance. I have a furnace near the tank with a bulkhead that goes right over one side of the tank.

Not sure if you can see it in my journal

Thanks for all of the input so far!

I'll try and get out to the swap&meet on the 24th.. maybe someone will be getting rid of what I may need.
