Ecotech Coral Lab info

CEReefer · May 21, 2020

I was reading the “report” about the Ecotech coral lab and their suggestions about the AB+ settings and how it grows corals beautifully, and I was just wondering, did any indipendent lab tested those claims? Obviously it is rather hard to test coral growth in different settings, as different systems can grow them at different rates depending on many other factors rather than light But.. Doesn’t it seem weird to take for granted the recommendations of a self-referenced “lab” paid by the company that actually sells that light? Is there any indipendent scientific study (better if in peer-reviewed journals) about what light, assuming same water conditions, grows corals better/faster?

That's a good question. They did a video on BRS TV on it so I'm pretty sure it's a good setting but who knows if it's been studied by a lab without compensation. I do run it on on my AI prime 16HD. Just set my tank up though and got the light two days ago so I don't have any results yet.

Right.. but you know BRS has to sell you the lights, also they didn’t have communicating systems, meaning if you have 3 indipendent systems you can’t guarantee there isn’t another factor inhibiting/stimulating growth, you gotta have connected system, sharing water/filtration to eliminate that variable.

The two coral frags imaged above started at approximately equal sized 1” frags from the same mother colony. Both frags were grown out in the same coral system under different lighting conditions holding flow and chemistry constant. Both of the images show sixteen weeks of acclimation and growth time. The frag on the left was grown under a 250w Phoenix* 14k metal halide bulb and the frag on the right was grown under the Radion® G3 Pro LED. The difference in growth between the metal halide and LED spectrum is clearly observable, but also very importantly to RW the coloration that developed under the Radion appears more intense. Additionally the white tips seen under the Radion® LED indicate the rapid growth rate of the colony.

Feel free to duplicate it..

2014.. Nothing changes..

Should I switch to Radion LEDs from MH/T5?

Looking for any advice from people with experience switching to LEDs from MH/LED set ups. I currently have a 40 x 26 x 22 SPS dominant tank that is still very young (around 6 months old). I have just finished stocking it with all my favorite SPS frags. So far things have been going pretty...

Well yea that's kind of a given. You cannot definitively say that purley the lights caused the immaculate results. However, Randy and Ryan know their s**t. They've been reef keeping for a long time and I would pretty much do whatever they say. If they went out and researched this on their own it probably holds some water... No pun intended. But that's my personal feeling. dang good question though bro Looking forward to the responses. I'm sure someone in this community will be able to give a good answer.

If only I had time, but science is what I do as a job. And can’t get manufacturers (or whoever sells them) results for granted, especially without any peer review. But that’s me. Same as saying “the biggest coral vendors (WWC, etc..) use them”, sure, they get them free or almost free to endorse them.. just wondering if any serious study was ever done as I couldn’t find any, but if anyone has any, please post it

WWC doesn't even follow AB+ to a "T". They use it as a baseline and modify it, as many of us do. Some openly share their profiles, some like to keep it to themselves.

I believe those wwc templates are obsolete now since the switched over to g5's. They should update or add the new profiles.

Point still stands (actually more relevant since coral lab was done with G4s, right?). G5 (blue)s were just designed to follow AB+ more closely, you can still tune them to your liking.

Also, not in the company's best interest to suggest suboptimal settings (at least to them). Makes their product look bad.

I suspect light intensity is more important than spectrum, at least for Porites lobata.

Effects of Different Spectra Generated by LEDs on Growth of the Stony Coral Porites lobata

Stony coral nubbins (tentatively identified as Porites lobata; see Figure 1) were exposed to light of the same intensity (128 µmolm²sec) but different spectra for 75 days. Growth rates were determined by weighing the fragments periodically with an analytical balance.
