So is it ok that my drivers make this noise and the leds crackle when dimming or is this something I should worry about?

Rockinzebra, I have the same tank I'm sure but curious about the fixture your looking at. Is it long so it goes the length of your tank or are you getting two fixtures that equal the specs you posted? Could you post a link to the lights in question? Thx

It's just the package I'm getting. I have to build the fixture. I think I'm gonna do like two big sections of lights on each side. Which would be 36 lights over only 24 inches which shld be more than enough. It's aquastyleonline.com

They are not worth the money IMO. The chinese fixtures will support sps, and you can diy an accent light with violets, reds, blues, and greens.

I would go for closer to 100 LEDs, and be able to support sps. With 72 LEDS, you will be okay with softies, and if you cluster them in the middle, you can keep sps towards the middle of the tank. Maxwellen drivers are the worst of the chinese drivers, they will buzz when dimmed, and are very innefficient. I would use meanwells instead, you can buy the dim4, a 0-10v controller (analog voltage!) for $85, and use that for a full sunrise/sunset effect with your LEDs. As for the LED colors, 10k whites will give you pastel colors, I always always always use 7500k cool whites, not too yellow, and not too white, plus they have a great 450nm spike, which helps to grow corals. I would go a little less on the regular blues, and add more royals and cool whites instead, 6 blues is all you need. Be sure to have that many colors on a seperate dimmer, mostly for the 6 reds, which can be a little overpowering.

Yes, you can, with a good enough heatsink, and lots of air circulation. Remember, heat is the LEDs worst enemy, do the more airflow, the more cooling, and the longer your LEDs will last next to your mh. I would do a 50/50 royal blue/420nm violet strip, mh does not have the 420nm spectrum in it, in most bulbs. With meanwells, I reccomend the DIM4, it is only $85, and will give you the full sunrise/sunset effect. If you ahve an apex, you can also program storms, however with royals and violets, it will not be much. I am against storms, as they do nothing but scare your fish.

I would not be worried, just annoyed, hyperion drivers will not crackle or buzz, and would only cost about $50
What do you think of these guys, for 199 are they worth it?
At $199 Reef Breeders Value Fixtures are the cheapest multicolor fixtures on the market

I would go 20 7500k cool whites, they are a little stronger than the blues. No 10k whites, maybe 1 or 2

I sell those, LOL, and yes, I have them over my reef tanks right now

For XTEs, 24 7500k cool whites, and 24 455nm royal blues, along with 6 reds, 6 violet, 6 blues, and 6 greens.

XP-Gs are about as bright, so no. You can just run them a little lower if you want to

What are your recommendations for a 36" x 18" x 15" tank with 14" water hight? Tank is SPS Dominant. Would you run 2 smaller fixtures, or one larger one? What would be the best mix of LED for the best growth and color? I do have various LPS on the bottom of this tank.

I would do 36 XTEs, 18 7500k cool white, and 18 450nm royal blue, 6 red, 6 uv, 6 blue, and 6 greens on a 24" heat sink
OP
OP
Yes, that exactly. 9 XT-Es per meanwell eln 60-48 d, that is the magic number, as they are 27v at 700 ma, and 45v at 1300ma, right in the drivers voltage range. I put all the colors on one, but you can do color specific if you wanted to.
