I have a blue LED strip come on first, that puts out very little PAR. I have 2 T5's come on 2 hours before the halides then 2 more an hour before. Then my 2 400w come on about 15 min separate of each other. All T5's stay on. The halides run for 6 hours. then 2 t5 go off 1 hour after then the last 2 an hour later. LED strip dims and goes out last 2 hours after the last t5s.

Hello everyone, as most of you already know CoralVue has taken over distributorship for Giesemann in North America. We are expecting our first delivery of the Giesemann's new range of T5 lamps in two weeks. I'm looking for three T5 only users to be beta testers for the lamps. For consideration please email me at chris@coralvue.com along with the following information:
1. Brand, length and color of T5 lamps currently in use?
2. Which fixture brand are you using, or DIY?
3. Size of aquarium and type of corals?
4. Please provide a current photo of your aquarium.
Three hobbyists will be selected based on criteria that we have already developed. All we are asking is for honest feedback on the look and performance of the new range of Giesemann T5 lamps.
Thanks,
Chris Conti

Wow nice deal. Too bad I have the spectra MH/T5 combo. What are the names and spectrum of the new bulbs? Ive ran giesemann bulbs for a while now, but been thinking of switching to ati bulbs.

That will be a great combo. I personally only run one fiji with 3 blue plus. But I like a more 20K look overall.

I've had Giesemann Spectra's for 4 years. Great fixture.
I have 3 of the 3x400W+4T5 units.
I run 5 400W Radiums and 4 400W 12K Reeflux. They actually look very similar. The Reeflux are just a hint whiter, so I run them at the back of the tank. (It's 6ft across, 8ft front to back and 3 ft tall). They make the back just a little more defined.
6 blue+ T5 on at 10am. Next 6 T5 at 11 am.( 2 Purple+, 1 aqua b special and 3 blue +).
MH on at 12pm, off at 6pm. Does anyone run their MH for much longer?. I think Chingchai runs MH for 10H.
I will likely run 6b+ and 6 coral+ next time. I think the extra white/ red brings out pinks much better. I previously ran 12 ATI Blue+ with 400w Reeflux 10k. Great bulbs. Corals love them- horrible white colour for me!. I then switched to Radium, the best light for me, but I think pinks and reds are a bit washed out though. Coral+ has a bit more red and blue than their white tube (Aquablue special).
Finally, I've been thinking whether the different combos available with T5 lights might be something to try and I'm thinking about a switch to the ATI T5/ led combo. There seem to be some good results with this unit?.....

Still a work in progress with 2 years or more to go until I think it will be "done" but just an updated photo showing how everything is progressing. I LOVE my fixtures!!
Hi Joe,
Why did you do a reboot?. Did you have coral probs or just got bored?.
I think you tried with much more t5's and fewer MH?. How was your experience?
Which SPS do you have now? Your blue tort was one of the best I've seen.
Cheers

Thanks Mo!
My tank was simply overflowing with coral and I had very little room to grow both literally and figuratively so I decided to start over and see if I could redo a TOTM worthy tank starting form almost scratch. For me corals are like fast growing Bonsai trees. A really good Bonsai can take 30 or 40 years and a really good reef takes 2 to 5 years if you grow your corals from frags rather than buy and place ocean grown colonies. That is the challenge I love and that is why I started over. I love growing colorful SPS and creating a reef that looks awesome. The process is most of the fun for me.
If you do your research in depth you will find that Giesemann makes the LEDs with the best spread of any LED on the market today . . . But, read my posts if you want to understand why LED light is not ideally suited to growing coral. All light is not the same when talking about photosynthesis.

Why is that? Otherwise it seems there's a lot of space between the separate color LEDs the Futura, which makes me wonder about possible disco effect. At the same time the Furura panels don't seem that large, which makes me wonder about light spread and possible coral self shadowing. Compare this with e.g. the GHL Mitras, where LEDs are arranged in tight clusters to prevent disco effect, while at the same time each cluster is separated from the other ones to prevent self shadowing.
(The above is just theoretical speculation, I haven't been able to actually see any of these fixtures in real life.)
I do think the Futura has the nicest looking enclosure design of the current LED fixtures, followed by the Powermodule.

Looks like disco shadows on the sand bottom (in the shaded areas):

In contrast this tank practically none, but then there's no shimmer either (due to less surface ripple?), and also seems to use less red light:

Does surface ripple aggravate disco shadows?
