[@Mike__B]

One thing I wish you would do, is test the PAR levels OUTSIDE the tank, to get an idea of how much light spill there is. Every time you raise the lights for new measurements you have to be getting more and more light that ends up outside the tank, which if you have a canopy over your tank isn't a big deal, but if it's open topped it can be a very big deal.

[@danieldoherty8805]

Hey, getting into reefing. I’ve an ai hydra 26hd that I got second hand over a 60 gallon cube. What settings would I need for a soft coral/ mixed reef? I also have a dilemma with regards to height. My light is only 6 inches over the water due to the canopy. Is there any way of diffusing the light for a more even spread or should I just be building a new canopy? Thanks

Hi I have a Red Sea Max E 170 I have the hydra 26 I think, I have Soft and LPS coral what should I get the light on at. Also when should it start and go off. Thanks

[@BRStv]

I would suggest using Randy's LPS settings for the 60 cube in your case. We usually set our lights for 30 minutes of ramp up, 8-9 hours of steady intensity, then 30 minutes of ramp down. Try to schedule this lights on time when you're home to enjoy the tank! 🙂

[@joerocha3482]

I have Red Sea 170max and have been running your AB+ setting since 2019 with pretty good results other then some algae here and there. I would like to try this recommended settings to maybe get better results. If i am going from the High setting AB+ to this new setting can i make the change all at once since it is less intense?

[@BRStv]

Generally speaking, a reduction in PAR is less harsh on coral vs an increase in PAR. As long as you're still providing PAR levels in the necessary ranges for the specific coral types you're keeping, you'll be just fine reducing the overall intensity slightly.

[@NRGizzer]

Do your spectrum recommendations also match for the hydra 52hd? Big german fan here of you guys, great work you do for us, thx :)!

I have questions, I have a 150 gallon tank I have 3 hydra 26 and 1 each t5 blue on each side. I have a mixed reef with duncuns, gold torch, hammers, zoas and and sps. My problem is my lights are in a canopy so I can only up 6-8 inches. I have 100% on blues & Uv, 6 on green & blue, 45 on whites. I think I'm frying my coral. One if my lps changed from red, green and yellow to green. Pc rainbow is turning green. What are your recommended settings for 3 hydras. 2 t5 blue in a canopy. The t5s only stay on 5 hours.

[@BRStv]

Honestly, without measuring the PAR to make informed adjustments the best thing you can do if you feel like you're lights are too bright is to reduce them about 20%-30% and see if that improves. The best practice overall would be to borrow/rent a PAR meter and then make your adjustments so that most of your tank at points in the top/middle/bottom are somewhere around 75-150. It doesn't have to be perfect and PAR meters are super easy to use, but knowing for sure what PAR you have in your tank will pay for itself in your corals surviving rather than losing even more. :)

[@JimRichardHartmann]

I just miss one thing.. I have a 60g almost cube, but near enough. I have 2 Hydra 26 HD's and spacing them that much as over that 4 footer is no option as half the lights will be outside the tank.. So Since you mentioned using more than one over a 60 for sps, a recomendation for spacing would certainly be welcome. What comes to my mind is using the spacing from 4 lights over the 4 footer , is that in the right direction.. Anyway it seems mounted the kind of really wrong now, with a height of only 8,5 inces and I did have a feeling that was a bit to low. Also I have them spaced by only 12,5 in the midle ending up 7,5 from the edge , measured from the midle of the lights, which is mounted the normal way so the pucks are placed in a row.. Any kind of thoughts on that are welcone.

If I have a 18x18x18 read sea 21g cube, does it still need to be 14 inches away from the water? Or will there be more light spill? Ai prime isn’t enough for my mixed reef

[@BRStv]

You'll likely find a decent amount of light spill if you mount the light that high over an 18" tank, but if you can live with it, it'll provide your tank with great spread. Of course, if you use a par meter, you can lower the light and intensity both to meet your tank's specific needs. Just keep hat inevitable hot spot in mind (which is why we recommend using a par meter).

That is the recommended spectrum mix at 7:55. If you need to turn the fixture down in intensity (like we had to do later in the video), you'll want to reduce all channels in equal ratio to achieve that goal.

Hey Randy how many lights you would suggest on a 150 gallon 7 foot long ??

We suggest 1 fixture for every 2 feet for LPS and 1 fixtures for every 1 foot for SPS. So, depending on your goals, you're looking at 4 fixtures for an LPS tank or 7 fixtures for an SPS tank given the 7 foot length.

[@TheDaannyy]

Thank you so much!

[@nicklutfi970]

@Randy R. How did you come up with the spectrum you ended up with? Is it just for par output? How does it compare to the AB+ spectrum? And last which spectrum would you use over your tank!

[@BRStv]

When there is no direct advice from the manufacturers on what settings to use we default to making our own based on maximizing the blues/uv/violet for coral metabolic function...adding in some whites until the tank looks good...then a bit of red and green sparingly. To some degree the AB+ is similar to this approach, we've just made it universal for nearly all LEDs that have adjustable color channels. Keep your eyes out for some more in-depth videos from Ryan and I about finding that optimal spectrum mix, coming soon!

[@salbishop7530]

Please do one for the hydra 52HD? Only see a recommendation video

[@BRStv]

Unfortunately we didn't have a spare Hydra 52 to be able to test it out. The Hydra 64 results shouldn't be too far off. Of course, using a PAR meter to test your tank would be ideal. You can buy, use, and return an Apogee MQ510 on our website with just a restocking fee.

[@DevilDog7564]

How would you adjust the levels for a mixed tank?

[@BRStv]

You could probably increase our recommended spectrum ratio equally across all channels to bump up the PAR in the upper portions of your tank. I would imagine that +20-30% for each channel would start to get you in those higher PAR numbers near the top of the tank. The goal here would be to create higher PAR zones near the top with pockets of lower PAR zones underneath and throughout the middle and lower parts of the tank...then strategically place your corals so the SPS is mounted up in those higher PAR zones, while the medium to lower PAR corals are in the rest of the tank. :)

Thanks.

[@robertwolters]

I think you should do a video explaining how you all come to all of these conclusions so some of us with say a 32 G biocube can rent the par meter and setup our tanks properly. Same with a massive tank. Etc... there has to be some form of algorithm you use so we can all calculate the correct placement.

[@BRStv]

I think the answer lies in choosing a goal for your tank. The target PAR numbers for coral types like LPS or SPS remain the same whether you are lighting a 20gal tank or 2,000gal tank. The key is to choose what tank type suits you best and then use the PAR meter to adjust your lights accordingly.

[@00Mass00]

Thank you for doing this! I don't understand why 14" is recommended over 12" ? It is more spread but also less par overall?

[@theaecombie]

Does this mean that these setting are recommended over the AB+ settings?

[@BRStv]

Using our updated approach to choosing a spectrum ratio, this is what we landed on. This newer spectrum provides a bit more PAR, but remains fairly close to those who have mimicked the "AB+" settings. I wouldn't imagine that one is going to be dramatically better/worse than the other and it's very important to verify any settings with a PAR meter to be sure you have it right.

[@jackiebowley8305]

The other ab+ settings that you recommended was much higher with the uv violet and blue. I think the uv was set at 118 and violet at 115 with blues about 80. These settings at 66 and 69 are much lower for lps and the settings for sps are still lower than the original. I ran the brs ab+ original with some growth but not fantastic. I had lights set at 10 inch above water. Mainly lps and softies. Hopefully now I will see better growth . Keep up the good work 👍

Won’t that high UV burn the corals ?? Way way way to high

[@BRStv]

In general lighting manufacturers use a "near-UV" LED that registers around the 380 to 400 nanometer range and call the channel "UV". I personally take this at face value because the percentage of the slider is not a direct representation of the intensity in that given spectrum range. For instance, a LED module may only have 2-3 "UV" LEDs out of the entire 26/32/52/64 or more LEDs that make up the light; 100% of those two LEDs are going to be far less "intensity" than 10-20 LEDs in another spectrum range.

@@BRStv an end to end review as you guys do for these please

[@joed8958]

They hard to find now , Everywhere is sold out

[@BRStv]

These lights have been discontinued in favor of AI's new Hydra 32 model.

[@Surefire67]

They pop up used almost everyday on Reef2reef forums. Soo many Hydras on there and occasionally new ones are on there.

I cant believe it needs to be 16 inches high!! That freaking sucks and is probably a deal breaker. I have been trying to decide for weeks which lights to get and I thought maybe I iwll go with bang for the buck for the type of light I can upgrade by adding more! I dont like the look of it being so high and would it still need to be that high on a 48 inch long but using 3 or 4 and only being 18 inches wide instead of 24. I i wsh you guys did more than 24 inch wide. Thats not real common either! If you are going 48 inches seems like 75 gallon or 9o are more popular and I would never just put 2 on a tank that big. It would look ridiculous! One day soon I promise I will quit asking you guys s om any questions about lights..sorry! Most men would have figured it out in in a few hours probably! haha Radions are starting to top my list! lol I wanted to save a few hundred! LOL.Do I need to spend more money for radions blutooth app or anything? Kessil and radion want to get ya for all they can it seems!

[@jakesreef1730]

Why dona test with a discontinued light and not the radion xr15 g5 pro? We have been waiting along time. This is stupid.

[@BRStv]

To help the people who have them :)

@@BRStv what about the people that want to add a radion but are waiting on the last video to decide which one to get..

[@vincentjames1995]

I find this a very helpful video, and it also shows that BRS is committed to helping customers and the hobby, and not just to making the most money and encouraging wasteful consumerism. Thank you BRS!

Ok.....

[@rasmuskok]

You never say for how many hours..

[@BRStv]

10-12 hours is a typical photo period with 0.5-1 hours ramp up and down at the beginning and end of that period.
