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 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.
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
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.
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!
Very interesting video as UV seems to be becoming the hot topic recently, thanks for putting this together! I can't wait to see the experiment on the effect of UV B. 😎

@@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.
You can never have too much light, and so many advantages to all the different kinds!! MH still a great standby for large tanks with sps dominate livestock
A lot of valuable information here, I too would like to see T5s in the mix. To pivot off of this content, it would be fun to see comparison of competitor fixtures as well!
"Let's walk inside since it's cold," he says, while I'm watching this with 4 feet of snow on the ground and -5F over here in Duluth, MN.....HA!!! Much love from the frozen tundra of Minnesota guys!
Thank you for the knowledge I can't afford but can understand as always thats a big issue I own a par meter but not a spectrometer, love the videos appreciate the information as always Mr.Sandler.
He sells metal halide bulbs, fixtures, and ballasts along with led accent lights for them. I believe he is sincere but unbiased? Judgement call. He admits there is no actual proof of the implied benefits.
Tullio with a frantic sales pitch after BRS videos out that say what Dana Riddle and others have said: UVA + UVB don't matter. The blue plus was one of the best T5's. basically zero UV.
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.
Loved Metal Halides but it was hard to keep the house cool. Something I saw in Indonesia is they only use UV over their tanks at least at the fish and Coral Market in Jacarta
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.
Reefing is one of those hobbies where you never stop learning all in order to pamper our coral babies!! Appreciate the video and information.
Quality unbiased content. The hobby needs more of this!
Why do you think someone with a warehouse full of metal halides and sells led accent lights for them is unbiased?
Tulio is so full of **** attributing theories to UV. Needs a sales.
@@jeffseussalias7605 Exactly, so many red flags

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

Great information that a lot of us don't pay enough attention to.
Glad to see y’all exposing these differences to the reef community! Would love to see more experimentation
more is coming !!
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.
Honestly I’m such a newby but I feel smarter after watching your videos Andrew.
Thanks Andrew and team for everything you guys do for the community!
appreciate that !!
That light spectrum analysis software is pretty awesome.
I appreciate these in-depth videos on tank tech! Keep it coming!
You learn something new every day
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
It is really cool to visually see the spectrums on the screen and the differences between the lights. Thanks for doing this video!
agreed. thank you !!
This video reminds me why we need the return of Freshwater and Marine Aquarium Magazine. Excellent job men!
Awesome video , explaining and showing the differances
thank you. more coming
Learning about saltwater and seeing how everything is and seeing progress it’s nice. Love the hobby
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!
pleasure. truth is we still dont get why we can run halides at higher par vs led.
Great video, thanks for sharing
Quite an education for somewhat who's only had small aquariums.
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.
T5's have little to no uv or any ir
uv b can go dn 20 to 40 ft.
@@PoloReef according to who and what data?
i have a uv under surface and spectrum how far down chart but cant put it on here
@@PoloReef By whom, though, so we could look it up?
Very informative in understanding lighting
I love learning about the hobby. Thank you for the video.
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!
we will be doing some real experiments with identical same systems different lights.
i payed more attention to this video than the attention i payed to my whole highschool years 🤣 love the info
good to learn more about par readings!!!
I am working on making space and getting a reef. They are just so cool, and you can foster alot of underwater life even here in this cold state of SD
Very interesting video as UV seems to be becoming the hot topic recently, thanks for putting this together! I can't wait to see the experiment on the effect of UV B. 😎
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
us too !! we will have duplicate corals with pathogens and see what happens

Great information. Thank you for all the work.
Interesting video. Thank you. Love these educational videos.
I love to see your videos and learning more and more everyday.
I love learning about this stuff!
Love learning more & more about this hobby!!! So many factors go into the saltwater hobby especially lighting with corals 😊
Quite interesting, love this type of video!
You can never have too much light, and so many advantages to all the different kinds!! MH still a great standby for large tanks with sps dominate livestock
Tulio has a Plethora of Info ! Thanks for this Super Insightful and Educational Video Gentleman 🙌🏼🙌🏼
Great information about lighting.
Love watching all the videos

Man all this is insane! I love this aquarium!
This is a great video. Thank you, guys, and awesome feedback, Tullio! ☺
Great Vid, very, very useful information.
Nice video. Keep up the great work!
Awesome content guys! Thanks for bringing great educational videos to the hobby!
Interesting video. I'll be curious to see future studies on how this impacts coral growth/health!
This was epic, I love the research and information shared. Thank you, Andrew and Rachid!
Another great video, loving the content!
Such great content Andrew! Can’t wait to meet you at FFM this year!
Great information. Would love to see experiment setups with fish and coral to see any affects between them. Great video!
I like yoiur ideas of using the reef
Thank you for the knowledge I can't afford but can understand as always thats a big issue I own a par meter but not a spectrometer, love the videos appreciate the information as always Mr.Sandler.
Very interesting Info! Thanks
Nice video, lots of good information
amazing work
I love the videos and the reef! What a system!
The amount of knowledge Tullio has is insane. He’s one of the most stand up guys in the hobby. And honestly cares about the hobby.
Knowledge, yes. Evidence and researched, no. He’s just reading what it says off a meter and making a case that MH are better.
It needs researching.
Not a bought review, fantastic job!
He sells metal halide bulbs, fixtures, and ballasts along with led accent lights for them.
I believe he is sincere but unbiased?
Judgement call. He admits there is no actual proof of the implied benefits.
@@jeffseussalias7605 well said!
Let em know Tullio! Thx for the video Andrew. 💯✅
I am surprised that MH temperature is so close to LED! Amazing!
Great information team 👍looking forward to more information.
Amazing aquarium
Love seeing everything you guys do!

Love the par meter!
we going to get one of those spectrum software machines
Bravo Zulu on this video. Great information 👍
Great information here
Interesting video
So interesting! Coolest tank ever
Very nice tanks!
great information!
great video
Great video!
Love the lights!
So...
Running uv with radion's are beneficial or not?
Marc sweating bullets filming this, hoping his LED fixture sales don’t go down 😂

I was waiting for this!
great video!
Very interesting. I usually shoot for a 150-200 average
So awesome!
Your CC guy needs to up his game....
Do you think a reptile UVB bulb might help augment LEDs, if it were implemented carefully?
Interesting , thanks for the video 👍👍

How much white light would you recommend I mainly use blues?
these are AMAZING
I would love to see your tests on t5s
