Lets See SPS LED Tanks!
 

Lets see those LED SPS tanks guys. I would like to see some before i take the dive into LED.

Ive never saw A nice colorful tank lit with led's. Mabye there out there. All the ones ive seen not nice looking.

I tried it once, SPS looked good and grew for a few months then started to brown out and loose color. I even noticed that my nice purple rock turned to a more gray color. Needless to say back to MH I went. FIY I was using Cree LED's 1/2 blue and 1/2 white independently controlled with meanwell drivers to get any color temp/brightness. PAR was not an issue either, they were spaced 2" apart on a 18" deep tank. I have yet to find a SPS tank that has made it long term (1+ year) with only LED's. MH are the proven and only way IMO to grow great looking SPS. LED's just have all the hype and energy savings. If anyone can prove me wrong PLEASE let me know

Yea I have seen the nices't sps tanks turn brown in months with led.

what about using royal blue leds for supplement lighting along with MH any positive outcomes? just for color pop.

i just read a post by a guy who paid way to much money for some LED's on his like 20gal ish tank and he thinks his zoa's love it.

but here is the kicker and common answer to the question he has only had them for a month. And no pictures of course

Exactly no LONG-TERM pics I had some high end zoos in the tank as well they seemed to do fine with the LED's but SPS definitely not long term. Using the blue Cree LED as supplemental lighting works fine I just don't feel that they can replace VHO actinic either though. Like I said I am open to anyone who can prove me wrong.

I read TONS and TONS of LED Build threads and have yet to find one of them a year later showing how successfull they are with SPS under them.

^^ agree.

i dont spend alot of time reading about LED's but has anybody herd weather or not they produce any UV?

LED's do not produce any UV. There are UV specific LED's but from what I know they do not produce the same wavelength UV that MH produce. I once thought that could be it but I have seen several great looking SPS tanks under HO T-5 only which do not produce any UV either. So I am still baffled why SPS do not grow well under LED's.

that's bad. I really hope that LED works, but it's a good thing i didn't jump on the wagon yet.

LED's do work...

The is a build thread somewhere on RC with LED SPS system, I'll see if I can find it.

Most people in this thread had LED SPS systems for 2+ years...

I want time lapse pics

That thread was a year old and i only see about a hand full of OK looking SPS tank. I really hope LED is good for SPS.

Wow, it almost seems like you have something personal against led's, lol.

Anyways, I have seen some smaller tanks that are full of color and has been led lit for close to a year.

I myself have been using all t5's for over a year and I have had awesome growth and color. Im currently going to convert to all led within a few months. Hopefully I can come back a year later and prove your wrong. (not trying to cause any problems or come off as a jerk, lol)

300g tank, 8x160W Maxspect LED for 4 months now. So far so good.:p

I have nothing against LED. I want LED to be the new "IT". I want to be through in my research before spending thousands upgrading my light and then have it not work and then spend hundreds more on t5 or Metal Halides.

Have you noticed any color differences in your system from switching??

I think LED works because I do see good growth even though I am having some issues with the tank. The colors did pop out before everything brown out, not from the led, but from phosphate.

I don't know if it's just me or the light is too white or because of the camera, but most of the LED tanks i saw the coral doesn't really pop. The color seems white and washed out.

I saw this tank:

well.... that's from the manufacturer. It doesn't count. It's not that i don't trust them... it's.... who am i kidding, ya, it's because i don't trust them.

Dang - I was hoping to do this...but if you're doing it and don't recommend....hmmm.

Can you elaborate why you don't think LED compares to VHO actinic supplementation? Output? UV? Coloration?
