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
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.
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!
"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!
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!
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
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.
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.
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.
4:32 Great work guys!!! It’s awesome getting to follow along the progression of the Polo Reef!!! I have a question though, what LED is this? Is it the one Tullio referenced in the pod on Reefbum?
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.
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.
i payed more attention to this video than the attention i payed to my whole highschool years 🤣 love the info
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
Thanks Andrew and team for everything you guys do for the community!
appreciate that !!
Glad to see y’all exposing these differences to the reef community! Would love to see more experimentation
more is coming !!
I appreciate these in-depth videos on tank tech! Keep it coming!
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 !!

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.
Honestly I’m such a newby but I feel smarter after watching your videos Andrew.
Awesome video , explaining and showing the differances
thank you. more 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. 👍

That light spectrum analysis software is pretty awesome.
I love learning about the hobby. Thank you for the video.
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.
I love to see your videos and learning more and more everyday.

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

This video reminds me why we need the return of Freshwater and Marine Aquarium Magazine. Excellent job men!
Great video, thanks for sharing
I love everything you guys do for the community thanks so much and keep up the good work.👍
appreciate that 🙏🏼
Quite interesting, love this type of video!
Great information. Thank you for all the work.
Loving learning something new everyday! Lots of valuable information here.
well see what it means. lol.
@@PoloReef hopefully something helpful.
Interesting video. Thank you. Love these educational videos.
Love learning more & more about this hobby!!! So many factors go into the saltwater hobby especially lighting with corals 😊
Very informative in understanding lighting
Awesome content guys! Thanks for bringing great educational videos to the hobby!
Tulio has a Plethora of Info ! Thanks for this Super Insightful and Educational Video Gentleman 🙌🏼🙌🏼
Thank you so much for this.

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.
Awesome videos! Keep up the good work guys!
Love watching all the videos
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

😂😂🤪
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.
I love learning about this stuff!
This was epic, I love the research and information shared. Thank you, Andrew and Rachid!
This is a great video. Thank you, guys, and awesome feedback, Tullio! ☺

Another great video, loving the content!
Quite an education for somewhat who's only had small aquariums.
Man all this is insane! I love this aquarium!
Nice video. Keep up the great work!
Some really great info, thank you!
I love the videos and the reef! What a system!

@@jeffseussalias7605 well said!
Such great content Andrew! Can’t wait to meet you at FFM this year!
amazing work
Interesting video. I'll be curious to see future studies on how this impacts coral growth/health!
Love seeing everything you guys do!
❤️🙏🏼

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?
Let em know Tullio! Thx for the video Andrew. 💯✅
Great information. Would love to see experiment setups with fish and coral to see any affects between them. Great video!
Love the new products
Watching this makes me wish I had the resources to do something similar.
I like yoiur ideas of using the reef
Very interesting Info! Thanks
I was waiting for this!
So interesting! Coolest tank ever

So much cope
This is beautiful.
Amazing aquarium
Love the lights!
Great video!
Love the par meter!
we going to get one of those spectrum software machines
Bravo Zulu on this video. Great information 👍
Great information here
Marc sweating bullets filming this, hoping his LED fixture sales don’t go down 😂
Very nice tanks!
Interesting video
great video
great information!
I am surprised that MH temperature is so close to LED! Amazing!
Your CC guy needs to up his game....
Do you think a reptile UVB bulb might help augment LEDs, if it were implemented carefully?
great video!
So awesome!

Thank you so much for the knowledge, now I know the mathematics on how much my body needs to produce vitamin D!
This is so cool
Very interesting. I usually shoot for a 150-200 average
I would love to see your tests on t5s
Awesome!!! 🎉
you guys ROCK!!!!
