"Shedding LIGHT" on REEF Aquarium Lighting

[@jacksonfamily1903]

Reefing is one of those hobbies where you never stop learning all in order to pamper our coral babies!! Appreciate the video and information.

[@candycaneunicorn8024]

Please do an update video halides on paper seems the way to go. A halide vs T5 would be an amazing comparison. Thanks Great videos don't ever stop.

[@juanmunoz8984]

i payed more attention to this video than the attention i payed to my whole highschool years 🤣 love the info

[@Alex_Correa]

Hey Marc... some of the things I told you on the phone when you switched to those Sky lights... Big mistake is the fact that you guys are concentrating only on UV and forgetting ALL THE OTHER QUALITIES of HALIDES! So important!! Thanks Tullio!!!! Nice shirt!!! Teaching all new and old hobbyists to understand the seriousness of reef lighting! Looking forward to see more and more of the other aspects of metal halides. Quality of light isn't only concentrated on UV as we know. Great beginning!! Thanks for sharing this video!

[@PoloReef]

now we are working on reds and infra reds as maybe important spectrum.

[@Alex_Correa]

@@PoloReef The whole spectrum works as an orchestra! It's not about separated wavelengths. Metal halide is the best source of light because the whole thing resemble the sun. Results don't lie. You won't regret.

[@jeremywhiting9009]

Glad to see y’all exposing these differences to the reef community! Would love to see more experimentation

[@kevindaniels8602]

It is really cool to visually see the spectrums on the screen and the differences between the lights. Thanks for doing this video!

[@PoloReef]

agreed. thank you !!

[@octiesreef]

The light's might be putting out different wavelength spectrums, but how much of that spectrum is reflected or absorbed by the water when you get 1,2 or 3ft down ? I would have liked to see T5's in the mix too.

[@jeffseussalias7605]

T5's have little to no uv or any ir

[@PoloReef]

uv b can go dn 20 to 40 ft.

This is super interesting, the use UVB has often been ignored, will great to see how your experiments progress. 👍

y'all know uvb pretty much filters out in the first few inches or feet of water right? its completely worthless, and studies suggest it may even cause more harm than good. uvb is what causes skin cancer and mutations in dna

[@Temptress1978]

I've used uvb for reptiles so this is very cool to learn about! Thank you for making this video and sharing your experience and knowledge!

[@PoloReef]

pleasure. truth is we still dont get why we can run halides at higher par vs led.

[@LAMNguyen-sd8mo]

Thank you so much for this. The question nobody is acknowledging if we need uv in our reef tank and the benefits for our coral and fish. Hopefully you guys can shed the light on this topic. Hopefully the led maker will take notes if the is beneficial effects. We want change!

[@PoloReef]

we will be doing some real experiments with identical same systems different lights.

us too !! we will have duplicate corals with pathogens and see what happens

[@jeffthomas7383]

@@PoloReef I'm hoping you'll test how different types of corals respond positively or negatively to UVB. Various SPS, LPS, Softies. Purely speculating, but I'd be willing to bet that not ALL corals will react positively from UVB exposure.

[@kbreef6430]

Interesting video. Would love to see future videos looking into penitration of uvb into water. How much of that is making it down 1 or 2 feet? If uvb only goes 6 inches in water and then dissipates, do corals in nature really get exposed to it? Interesting topic and I look forward to seeing more.

[@MAR1N3GUY]

The big question is… where on the spectrum are Andrew and Tullio?

[@drizzieee]

So awesome!

[@vascojardim6703]

Great video! To anyone who says that there is no scientific evidence that UVB is even necessary I would ask what is the scientific evidence behind saying UVB doesn’t matter? If your reply is “look at all these wonderful LED lit tanks” my answer would be “look at all those wonderful MH tanks “. I would also venture to add that MH tanks tend to last longer. As others have said, I would have liked to see T5s as well.

[@siggyincr7447]

Tulio is very obviously a big proponent of the idea that UV is important for reef keeping. He seems to be channeling his inner infomercial presenter here. And as far as I can tell there are some pretty good arguments that it MIGHT be. But, loads of successful tanks without UV show that you in fact don't need UV.

[@PoloReef]

agreed. it was just meant to show led halide difference including other spectrums.

[@craftaquatic6472]

A few points have me thinking here. Some of us carbon based lifeforms need UVB to produce and synthesize vitamin D. Wonder what it actually helps the fish and coral synthesize. There was a mention of a lower prevalence of water born bacterial issues in the aquarium, when most reef hobbyists were primarily using MH. Very interesting, if true. I’d be interested in hearing more about how high quality UVA/UVB supplementation, to our existing LED/Hybrid setups might benefit our reef ecosystems. For instance having a single UVB/UVA fixture mounted and on an hour or two a day.
