Jackie I currently have a 30l x 24w x 24 tall tank and I have an ATI 8x24 w dimmable. I also have a light bar with with 3 420 nm true lumen leds for night lights. With only 4 tubes you are very limited with color choices. A 4 tube fixture is plenty IMO but if you can afford a dimmable 6 tube I would do it.....Especially if you plan on SPS , besides you can place the fixture high and ramp it up. I currently have mine about 12 " above the water surface and run at 80% of max power with no issues . But I do focus mainly on SPS but all my sand dwellers do great!]]> Sun, 19 May 2013 03:44:04 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=64459&PID=523616&title=how-many-bulbs#523616 http://www.utahreefs.com/forum/forum_posts.asp?TID=64459&PID=523585&title=how-many-bulbs#523585 Author: bstuver

It does have to hang pretty high because otherwise it doesn't look good and you can't see in the tank well.
If anyone has a fixture to borrow for a day or two so I can see if I like the look that would be great.]]> Sat, 18 May 2013 18:58:39 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=64459&PID=523585&title=how-many-bulbs#523585 http://www.utahreefs.com/forum/forum_posts.asp?TID=64459&PID=523581&title=how-many-bulbs#523581 Author: bur01014

tough choice, reason being- your tank is somewhat shallow, I think a 6 bulb would have to hang quite high, I'd probably do the 4 bulb, especially if you supplementing with leds.

I had my sunpower 18 inches above one of my old tanks (12 inches shallow) in order not to bleach corals, it was a 6 bulb.

If you plan on putting 2 led strips also, 4 bulbs would be more then fine. But more color options if you go with 6. Its all up to you]]> Sat, 18 May 2013 17:30:13 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=64459&PID=523571&title=how-many-bulbs#523571 http://www.utahreefs.com/forum/forum_posts.asp?TID=64459&PID=523569&title=how-many-bulbs#523569 Author: Mark Peterson

Aloha Jackie,

My thinking is that, with only 12" depth and where I seem to recall a recent post where you indicated you're steering away from SPS in this tank, 4 tubes would be sufficient.
Of course (you know I have to say this ), the closer this tank sits to sunlight, the less artificial light it needs.

Have fun,
Mark

I am debating on going with a t5ho set up on my tank it's the zeroedge tank and measures 30" long 18" front to back and 12" high.
Would you go with a 4 or 6 bulb unit? I also plan to build a floating type canopy to hide the fixture and want to add probably 2 445nm/Magenta panorama pros to get the pop I like. ]]> Sat, 18 May 2013 13:46:31 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=64459&PID=523549&title=how-many-bulbs#523549
