Korallen-Zucht T5 Bulb "Great Barrier Turquoise"

[Koigula]

I think you are chasing a ghost that does not really exist is what I am saying. The worst thing you can do is alter your par output because you are bored, along with duration of lighting. If you pick this tweaked spectrum, believed the marketing hype, and left it along for a year, you might have benefit. (or not)

More measurable effects in SPS are known to be effected by increasing flow, or stabilizing alk.

Ill stop there. It is your hobby in end.

I own a par meter. I am capable of manipulating the spectrum of light without changing the par numbers reaching my coral.

And I had to dig quite deep to discover the existence of this bulb that no one in my country is selling. If that is marketing, then they're doing a terrible job at it.

Ok Just realize you manipulate it once and leave it alone. Keep changing it it terrible. Dana kept stressing flow and reducing boundary layer at corals is more important than perfect lighting.

Local club had Dana Riddle do a Zoom call here. I never join them so was good to see.

I know that flow is important. I've also read about reducing the boundary layer around coral. In order to accomplish that I have alternating gyre flows, standing waves, and pulsing flow represented in my tank. Did you think that I was ignoring those things and only focusing on my lights?

It's also worth noting that just because flow is more important than spectrum does not imply that spectrum is useless to think about. One can tackle the most important problems and then also tackle other problems of lesser importance.

It feels like your goal is to convince me that I shouldn't care about light spectrum, and I really don't understand why you have such a hard time just accepting that it's an important part of my personal enjoyment of the hobby.

It's not. Bulkreefsupply does not currently sell the bulb that I referred to in the thread title.

Here is the bulb that you linked to on KZ's website. Superblue 39W

Here is the bulb that the thread title is referencing, also on KZ's website. Great Barrier Turquoise 39W

You can ask BRS to pick up a case. They are not paying much attention to T5s anymore, so a smaller company might pick a few cases.

That is not the case. I am making assumption that you are fairly new and pitfalls are rapid changes to tank. I prefer hobbyist have a wide range of lighting options. I will admit I am not pleased with BRS and ECCOTECH domination by glossy adds. It is way of the internet though. It is important to distinguish bleed edge technology and marketing hype.

There are 100s of pigments that light up in different ways. Red fish look black at 50 meters of depth. Incredible blue corals are easy to get now that everyone is obsessed with blue lighting. There are lots of trends.

I did reach out to them a few days ago. Last I heard was that they were going to discuss wether or not to carry this particular bulb. They do carry other KZ bulbs though, so it shouldn't be too much extra effort to add these the next time they order bulbs. I have reasonably high hopes.

How are you defining 'new'? My account here on Reef2Reef was created in 2017, and I was keeping saltwater aquariums for a while before I created this account. My introduction to the hobby was from NYSteelo on YouTube, which was maybe10 years ago at this point.

Why would you go into the area of the forums specifically intended for the discussion of lighting topics, and into a thread that was dedicated to discussing a specific bulb and a specific photopigment that it might activate, and then start trying to educate me about other random topics? There is a "New to Saltwater" area of the forums for stuff like that.

That's true, there is a solid peak in the cyan range. I've seen those graphs of 6500k T5s before, but I hadn't yet connected the dots that they had a decent amount of cyan.

Unfortunately for me you also get a big peak in the red range too. The extra red would run counter to my goal of simulating the ocean at something like 10m to 30m. It looks like it could be a great choice for tanks that simulate shallow reefs, like acro tanks usually are.

Red is very important,

At 30 meters underwater in a coral reef? Why do you say that?

You need to look at some relatively cheap high CRI led Cobs..
6500k Bridgelux..

BXRC-65S4001-C-7x
34.4v @ 1170mA. 4508 lumens.
$12.57 each,

For corals..Depends on what depth you want.
Still close to 6500k though with the slight red bump.
