Hello all,

Need advice on a new T5 fixture for 48x24x20 tank. "MAINLY SPS"
Tank has a Bean Animal Overflow so it's 20" wide display.
Is 6 bulb fixture enough or I should go with the 8 bulbs? I like the dust to dawn effect so I'm leaning towards the dimmable fixture. When they just came out I heard a few issue with the ballast and wiring issues but I think they resolve these problems.
Please advice, Thanks Rob

Hey

I think the 6 bulb would work for you, but if your budget allows the 8 bulb would be nice. You might also want to consider adding some reef brights to the fixture. I have the 6 bulb dimmable on a 65 standard tank and am very happy with it. I also have one reef bright on the back of the fixture angled towards the front of the tank. The extra pop is really nice.

Thanks for the input, reef Brite not a bad idea. What are color bulbs are you using? Anyone using 8 bulb on similar dimension?

I have a dimmable 6 bulb over my 110g. 48x24x22 and it is more than enough light. I actually cant run it passed 70% my sps lose color. Im still trying to get color back to them. The light output is unreal. Great fixtures. TBH an 8 bulb will be overkill.

If your corals are bleaching I think you should raise the fixture a little and slowly acclimate the corals to the light. There is no reason you can't be at the point where you run them at %100. There's plenty of threads with guys (with amazing success) using 8-10 bulb t5 fixtures. Some even putting reef brights on these in addition. I think the 6is sufficient, but being that this tank will be sps dominant and you have the space I wouldn't rule it out because someone says it would be overkill.

Not that I'm ruling out the 8 bulbs but was thinking about attaching reefbrite to the 6 bulb fixture. If I do the 8 bulbs I'm thinking about removing the 2 center bulbs and run LED in the center.
