Looking good man! Been enjoying the videos. Sub'ed ya...

So I ended up modding the Ocean Revive T247 fixtures. I swapped out all my cool white 10k diodes for warm white 3.5k diodes. I also replaced the useless red and green diodes for the warm white diodes as well.

I wanted to have a better useable spectrum and get rid of the Windex look I got from my LEDs as they are too focused on the blues/whites. I missed the warmer colors I used to get (red/orange/yellow) with my MHs.

 

[FarmerTy]

Let me know what you think of the warm white LED swap.

Here's a video I took a couple days ago after the swap.

Here's the video I posted a couple days ago with the old cool white LEDs.

Odd that it didn't embed.

I thought you were adding in T5s? They should supplement your LEDs as far as spectrum is concerned. And I always thought that the greens and reds were worthless as well, yet when you look at the spectrograph of the white MH and T5 bulbs, they have massive spikes in those areas.

 

[FarmerTy]

Still adding the T5s, I actually have all the equipment for them but just need to get around to installing them.

It's debatable whether there is actual function to the reds and greens as their wavelengths aren't shown to be used primarily by the coral symbionts. They are represented in certain T5s and MHs but visual appearance versus actual utility to the corals is the key question. Dana Riddle actual has run an experiment with red wavelengths and when a coral is exposed to just the red spectrum, the flesh recedes and dies. While that doesn't mean all red spectrum is harmful to coral, seeing that it isn't particularly useful and seeing that there is possible detriment to having too much has convinced me to go ahead and remove it. It is even suspected that red and green spectrums help algal growth but I haven't researched enough on it to make any real conclusions.

 

[Cody]

Green literally has nothing to do with algae growth, but red has a lot to do with it. This is due to chlorophyll. The reason that plants are green is because they're reflecting the green light that chlorophyll doesn't need. However, corals have some chlorophyll in them, if I remember correctly. I can get into that more if you're interested. By switching your cool whites to warm whites you have effectively shifted your LED spectrum towards the reds, as opposed to the greens. As far as the effectiveness of red and green LEDs in comparison to their T5 and MH counterparts, they typically don't hit the same peaks of the spectrum that T5s and MHs do. I'm not claiming that's there's any rhyme or reason to these peaks, but we all know that those light sources are proven and they definitely peak hard in those areas. The peak of T5 and MH is more correlated to what's called a Lime LED and the red peak is more in line with what's called a Deep Red LED.

 

[FarmerTy]

That would make sense about the green LEDs. I got a flashback of freshmen year all of a sudden and my biology course.

I do remember reading some research regarding chlorophyll detected in corals, but the discussion of it escapes me right now at this hour.

I definitely wanted to shift my spectrum to the lower kelvins and then supplement with more actinics with my T5s. More so, I wanted a more balanced profile than just 10k and 12k whites combined with royal blues and blues with some violet thrown in there in the Ocean Revive fixtures.

I briefly looked into the lime diodes but once I saw that they really don't add a significant amount of measurable PUR, I opted not to look into them any further. I did catch that they are excellent for color rendition.

One of the best and most colorful reefs I've seen is running nothing but a 50/50 combo of 10K White and 470nm Light Blue Actinic Lamps. Just google super natural reef. Jake adams is asked in the comment section what bulb combo their running and tells exactly what i've written above.

Gorgeous tank for sure! Keep in mind they are using T5 bulbs. 10k T5 bulbs will generally have peaks in the 440nm (blue), 520nm (green), and 620nm (red). When dealing with LED diodes, we're getting a really focused spectrum for the most part. The green and red diode I removed were emitting basically mostly 520nm and 620nm. My warm white is generating 3.5k (roughly 520nm through 680nm) only for the most part.

Ok got ya. If you want me to bring over a lighting expert, let me know. I know a guy on RC who's very knowledgeable when it coming to spectrum, bulbs, fixtures, etc.

New light rack I've been working on. I finally got a chance to add T5s to my LED fixtures to supplement color and coverage.

I used shelf track from home depot.

Rubbermaid 70 in. Black Twin Track Upright FG4B8900BLA at The Home Depot - Mobile

I used the pieces and constructed the light rack. The 3 LED fixtures siting in the middle are the Ocean Revive T247s with all the 10k, green, and red diodes replaced with 3.5k warm white diodes. The T5s are run with ATI ballasts and are 80w, 60" T5 bulbs. The two front ones are ATI Coral+ and ATI Purple+, with a single ATI Blue+ in the back.

I call it my ATY Poorman's Powermodule. [emoji23] All I have to say is holy moly, it's bright!

 

[FarmerTy]

Guess the ATY Powermodule joke will only work if people knew my name is Ty.

Light looks great

It's funny that I just read this considering that I hung some lime leds tonight. Doesn't do much for the corals, but does a lot for me. Anyway, how are you liking the T5 combo? What bulbs are you using?
