If you love acropora, clams and leathers, 6500k is your best friend. Also, anyone who loves softies would benefit from that light.

That’s non sense! I’d really like to know who came to that conclusion or termed the phrase “white lighting grows algae” We grew everything with halides which were yellow and white! I left for awhile and came back to the windex hobby haha!
Interesting experiment. I'm going to have to follow.I was a fan of blue lighting.
However, I recently challenged my beliefs. I did some reading from people I respect in this hobby.
I’ll give some quotes on what changed my opinion.
I’ve always felt standard reef T5 bulbs were
lacking in the red (660nm) for photosynthetic shallow water animals. I also currently believe the lack for yellow/amber light cause corals to lose their chromoprotein pigments overtime, like the “battle coral” phenomenon.
I did some searching on 6500K full spectrum T5, and I’ve settled on the Giessmann Super Flora bulbs because I really that spectrum, specifically because of that red peak at 660nm. The high amber/yellow also helps a lot.
Edit: I’m actually going to try the Tropics because too much red might cause bleaching in corals. The tropics is what most people use for 6500K, including Adam from Battlecorals in his T5 tank.
I’m going to mix in a few in my fixtures to see if there are any noticeable changes in my aquarium.
The all red oneWhich bulb are you referring to? The one in the OP or the all red light someone suggested for an experiment?
My 260 gallon tank uses 2 fixtures of ATI 8 bulb 54watts.Interesting experiment. I'm going to have to follow.
How many bulbs does your fixture hold?
What other bulbs with the 6500k?
I have been thinking about adding (4) t5's to my Reefbreeders light.
I have 2 types in my cart at Amazon.
Wave point 12000k and the ATI blue plus.
Not sure if it would be better to run (4) 12000k or have the blue+ mixed in.
The tropics came today.My 260 gallon tank uses 2 fixtures of ATI 8 bulb 54watts.
I’m going to be using this bulb combo in both fixtures:
3 blue plus
3 tropic 6500K
2 Actinic
Oh, that looks pretty good!The tropics came today.

Can I suggest this:@Miami Reef what would you recommend to get a similar spectrum with the 6 bulb?
blue+
Actinic
6500k
6500k
Actinic
Blue+
I am concerned it might be slightly too "white" in overall spectrum
I can confirm that from personal experience! Then I seen a video from reef builders with jake Adam’s also explaining it perfectly,just 1 week late for me ! He talks about little amounts of soft warm light having a great benefit on bright red /orange and pink corals like Monti, acro ,scoli, and acan. Only in low amounts during high photo periods,. He saw crazy benefits to the rare pink red orange coral. Again low amounts he said I believe his reds maxed at 15% but he cautioned not to spring it on your fluorescent coral in any quick fashion if they have bin on a mostly blue schedule! Right after I did literally 2 days prior watched my teal hammer my most unique hammer that was thriving! Barf brown zozantheli after only a couple hours of soft white (minor red- green) with white led at only 15% ! It never recovered and my gold hammer did the same just took a day longer because it went from golden to dark yellow to maroon then barf brown zozen deflate and rip! But it’s because I had the blue fever! And didn’t transist slowly ! I am now looking at going more natural sun scedual mixed in with my blues at very low intestines. Like Jake# TheLateJakeAdams!Rip! Tried to teach me!Oh geez. That’s a lot of red. I think that’s too much red.
Here’s the T5 spectrum for one of the bulbs you mentioned:
I don’t know if I’d want to experiment with that much red.
I'm trying to choose the T5 to replicate the natural light of the first meter of the reef... Like the picture..The tropics came today.

This is the natural spectrum @ 1mI'm trying to choose the T5 to replicate the natural light of the first meter of the reef... Like the picture..
For you.. It's possible?
Using 50% e 50% blu plus and 6500 maybe??
I think that the light in the first meter is white, yellow but with a little azure mix...
Aquablu special is not that light..
Blu plus is blu
Coral plus.. Hybrid with blu and Terribile pink
Tomorrow I'll have the 6500 osram...
I want to try... 50/50 6500 and blu plus.
