Dumping LEDs. Back to T5HO we GO!

8 posts in this topic

So I have taken the plunge to dump LEDs and go back to what just works, T5s. Waiting on the fixture to arrive next week. Here’s a video of my tank with LEDs for the last time. 
 
 
Hamilton Lighting Tech was having a great end of year sale so I picked up their 3ft 6 bulb fixture. 
 
The light from any LED fixture that I have used just seems to be harsh, in a word. I have always experienced success when using T5HO fixtures.

I had a long run with LED's before finally switching back to T5's.. It's made a huge difference in growth and color for me.  I'm sure you won't regret this decision!  I've tried Kessils, Radions, and the Black boxes.. all of which produced pretty good color, but not like T5's do.  My previous bulb combo for the 6 bulb fixture I have was 3B+, 1UV, 1C+, 1P+ (all ATI).  I had really good growth and color with that combo.

 

I recently added two Reefbrite XHO's onto my fixture to add a little more blue saturation and allow corals I sell out of that system to adjust more easily to tanks that use LED.  My new bulb Combo is 2 B+, 1 P+, 1 C+, 2 UV, and the 2 Reefbrites on 50%.  The corals took awhile to adapt, but I'm getting a pinch better color with the extra blue saturation from the Reefbrights.  Hopefully some of this info is useful for you!

Yeh I am currently running 2 b+, 1 c+, and 3 uv.  The polyp extension in the LPS has been phenomenal and the corals are starting to grow, mushrooms are popping out babies left and right lol.

Still getting good results with the T5? better color as well? I am thinking of supplementing my led's with a 2bulb or switching completely to a 6 bulb for my 75g

I recently made the switch.  My experience is anecdotal at best since I made the switch after a tank crash that took out 99% of my acros.  LPS were unaffected by the crash and I've seen improvements in their health and color since the change.  After making the switch I did see noticeable improvements in PE and color in the few remaining acros I had.  My green slimer has more PE than I've ever seen from it even before the crash.  It does seem that my new acros are encrusting more than my old ones were. 

 

I will say that I am glad I made the switch if for no other reason that not having to worry about the light portion of maintaining the reef.  I no longer have to worry about whether or not the lights are "correct".  Intensity and color channel settings have been removed from the equation.  It's a really nice feeling.  I also enjoy the look of T5.  I managed to get a bulb combo that I am happy with on my first attempt.

 

I was worried I would miss dusk/dawn but a pair of actinics on my 2 bulb channel has kept me happy so far.  I previously had a pair of radions and then added a 4 bulb retro kit.  I have restocked the tank with a load of new acros so I'm looking forward to seeing how they do under this lighting.

Nice!

 

The light from T5 seems to be soft, where as the LED light is so focused that it seems harsh. I wonder if that could explain the better PE. Just about every reefer who made the switch from LED to T5 has reported better PE

I currently run a Zetlight UFO on my nano.  Single chip array similar to Kessil.  My coral do OK under it but if I try to turn it up any more (Im currently at 65% blue, 20% white, 10%red and 10% green) at the peak of the daily cycle I notice bleaching and some get very pissed.  I have a 120 in the works and after doing much research have purchased a 4 bulb T5HO fixture and will supplement it with 2 reef brite strips or some DIY reefbrites, havent made up my mind yet.  It seems that is the way to go other than T5 and halides.
