SPS Lighting


I'm curious. Is LED lighting sufficient for sps corals?

some people have had "good" results, with LEDs

but I have not seen MH or LEDs get the growth rate that happens in the wild... I have seen some MH get close..

SPS do well under LED's. See my tank for evidence.

Its doing okay. Growing slowly because of the low nutrients. Healthy though.

The best lighting for sps is definetly MH. LED are very good butare still new and full of problems. Many peeople have succsesss with led but for how long with this succsess remain?thats the question i asked before i got my lights. Alot of people have had sps die under leds after a year for some unknown variable that people havnt tweaked yet. Metal halids are more trust worthy and simulate tge sun and growth alot better. My mh are awsome, and i recomend it all the way. Try to get atleast 5watss per gallon for sps.

Also forgot to mention that 14000K is probably the best spectrum for corals as it gives them amazing color and great growth.

Don't you have to replace your MH light every year or so? Also, doesn't it use up A LOT of energy and create heat that raises the temp of the water?
Which brand do you have?

Your right. It makes a ton of heat and i have to replace every 10 months. LED dont produce heat, dont take alot of energy, small and last awhile. The problem as i dtated above is that led's arnt "reef ready" I simply meab that there too many things unknown about how long they can give good light etc. If anybody has kept sps under leds for more than 5 years please chime in. My Metal halides 2x 250wat cost about 20 bucks amonth. Thats not too bad for the benefit they give. The heat can be counterd by a simple fan or placing the lighta over the aquarium 6 inches which i what i do and i have 0 temp change in tank. If u wanna know how to keep halides from heating up a tank i can tell u all the tricks if u r really thinking about mh.

Well, right now, the setup I have has a fixture for a MH, and with the canopy it would be over 6in. I also have a chiller, so again I wouldn't have to worry about the temp. increasing.
The lights I have on right now are PC: 55W 10000K White light and a 55W Actinic light.

It really depends on Par levels and the spectrum the LEDS put out, in all fairness ANY light will grow corals if the proper intensity and spectrum is achieved.

Your right, I'm just trying to figure out what would be the best kind of light.

I'm not an expert, but what you want to look for is an modular LED system, so if you don't have enough light, you can add onto it, and if a single LED burns out, you can replace it without having to replace the entire fixture.

Budget really effects what you can get.

EcoTech Marine Radions are proven to be the top of the line at this point, but at $749 a pop, its a true investment. Some what of a gamble too as they are relatively new to the market.

Ecoxotic LED Stunner strips are good.

I've heard many good things about the Aqua Ray, Aqua POD LED

Personally, when I begin my build I'm going with a DIY LED fixture from Rapid LED. Make sure you get a good brand, and a time tested brand as well. Just stay away from gimmicks like the Marineland Reef Compatible LED.

Also, if an LED fixture looks TOO good to be true for a price, It probably is.

I was looking into the Aqua Sol, and it's a modular. That is about $500, also an investment. There's no way I can build a DIY fixture lol, I know nothing about that stuff, but I do have a friend who might... Are DIY modulars cheaper? Also, what about setting the lights at certain angles? I've read about some LED's and they have like 70degree angle lights, or 30, etc. How does one go about doing that?
