At the 8:30 point, I see the space recommendations for 4 hydra 32s on a 48in, SPS dominate tank. Would 3 hydra 32s work for a 48×24 tank but instead, a mixed reef? If so, what would be the optimal spacing and height?

[@Mike__B]

Thanks for the info. Something that may be useful in the future is to show one light on a 4 foot wide tank just to see what happens in that 2' x 2' area when you don't have reflections from the sides, while I know one of the more common configurations of tanks is in 2 foot increments there are quite a few of us who have 30" front to back depth or even 36" front to back depth so knowing how the light behaves when it probably isn't going to be bouncing off the glass would be a nice piece of information to have. And not having that within 75% PAR rating isn't necessarily a bad thing, I really don't want corals within 6" of the glass because I know they'll grow closer to the glass and cleaning becomes a frag creation event then.

[@BRStv]

At 8:15, you show a photo of the lights with their long edges oriented to the front and back of the tank, then in the graphic at 8:35, you show them oriented to the sides of the tank. Then at 9:03, you show a photo of the long edge of the light oriented to the front and back again yet at 9:12, the graphic shows them oriented side to side again. which is correct? In the 4' tank in your example, should the lights have their long edge oriented front to back or side to side?

Sorry for the confusion. Our recommendation at those points in the video are to run the lights from front to back. In other words, perpendicular to the tank's length.

yes and no... while he explains that hydra 32 will not cover SPS full tank... you can use it with a mix tank just look at the PARs above 200 and place your SPS corals there... if you want to do SPS full tank either use hydra 32 in combination with T5 or look at his video on the specific hydra 64 since you cant achieve full SPS corals tank with just hydra 32.... hope it makes sense for you

[@catseverywhereat5643]

What would be the spread for a 60" inch long 100 gallon tank? And how many 32s light would you recommend?

[@BRStv]

We would suggest 1 Hydra 32 per 1 foot of tank length for an SPS dominant system, or 1 Hydra 32 per 24" for an LPS system. For your 5 foot tank, you'd be looking at somewhere between 3 and 5 Hydra 32's, depending on the types of corals you'll be keeping.

I’m just curious what is the best coral light that does the job but on a budget because I want to opportunity to have a mix reef but I just want to do a softy tank only

[@AnimalKING]

How deep in the tank were you taking the par measurements.

[@BRStv]

For the mounting height test we take a grid of measurements at 6"inches below the top of the tank. For spacing we are taking measurements directly in the middle of the tank at 12"inches below the top. Both 60 and 120 gallon tanks are 24inches tall.

[@atfinthehouse8631]

Nice job, very detailed info. One Hydra 32 at 14-15” set in middle of IM 30 Long?

[@BRStv]

36"inch coverage might be a stretch, but could be doable for LPS and softies knowing that the outer edges will likely be pretty low. You could crank it up and mount it a bit higher and see if you reach your PAR goals.

[@markroberthon]

Hi, and thanks for the video! It's hard to find this type of info, and you guys explain it perfectly! I have a hood on my tank, and can only mount the lights 8" above the water, and there is also a lid on the tank. If I am aiming to do a mixed reef, how many Hydra 32s do you recommend, and at what intensity?

[@BRStv]

You don't mention your tank size, but given that you're trying to mount the lights closer to the water surface, you're almost certainly going to want to add in an extra light fixture or two, but turn the intensity down. This will give you the extra spread that you're losing by mounting the lights closer to the water.

Hi, great video! I am looking for lights for my reefer 250 and 2 hydras 32 sound like a great option! Also considered 2 Radion xr15 gen 5 or an Orphek Atlantik v4. I am going for a mixed reef. What is your suggestion and, in case I go with hydras, what spacing would you suggest? Thanks in advance for your time!

[@BRStv]

Two Hydra 32's would certainly do the trick! Spacing gets a bit tricky to try and predict. You could always start with them evenly spaced over the tank, but most likely the "optimal" spread will have them spaced a bit further apart from each other. The only way to be 100% certain is to check with a PAR meter. :)

[@bluerider0988]

Are the PAR readings taken from the top or bottom of the tank? (Looks like bottom from video) If from the bottom how deep are the tanks? I also hope you can figure out a way reinstate the par meter rentals. I think it is a great tool for us hobbyists. Thanks again.

[@BRStv]

The mounting height tests in the beginning are based off the par levels 6" below the surface. Towards the end of the video, you'll see par readings at 6", 12", and 18" below the water surface

This is all to hit a specific par goal. If your tank is a different size, you may need to us a par meter to measure the par you're seeing at the setting you see here and adjusting up or down to meet your needs.

[@chrishawkes8688]

Really useful, I have a question. The video states optimal height of 14 inches for the 32 and show the HMS mount which is what I have. I presume the measurement is taken from the top of the bracket, not from the lenses as the bracket isn’t long enough to extend to 14 inches?

[@BRStv]

Unfortunately the bracket isn't quite tall enough to reach our BRS optimal mounting height, so if you're using it, just try to get the light as high off the water surface as you can.

What do you recommend for 30" x 13.5" x 18" tank for softies / LPS and mounting height? will 2 hydra 32s or 1 hydra 64 be overkill

For that tank size and softies/LPS, I would actually suggest going with two of the AI Prime fixtures. It'll get the job done and even save you some money :)

What about two Hydra 32s on a 40 breeder? SPS tank?

That'll work, but probably overkill in most situations. Going with three AI Primes will be less expensive and still get you the PAR you need for an SPS dominant 40B.

[@fishstix1988]

at 8:34 should the hydra 32 lights be front/back or left/right oriented? I thought I saw in another video about having them front/back oriented.

[@BRStv]

Because of the rectangular design, you will have more left to right spread if you mount them left/right oriented. Most will likely choose to run them in this configuration to spread the light more evenly across rectangular tanks. :)

[@duncantse]

I think something that you left out is the settings and par readings for a 24"x24" sps tank with only a single hydra32hd Great writeup tho!

[@BRStv]

Our goal for SPS dominated systems is to blanket as much of the tank from top to bottom in PAR ranges between 200-350 as possible. Given the mounting height for optimal spread and only 90watts of output, we found that a single Hydra36 (on its own) just doesn't have the output to achieve those ranges in a 24"sq inch area. Because of that, our recommendation is to add in some T5 supplemental light or upgrade to the larger Hydra64 to reach those goals. :)

[@duncantse]

@@BRStv Oh okay I see your point. Thanks!

[@volteface69]

Merci pour ta vidéo !!! 👍👍👍

[@Brmmsilva]

So, am I right to assume that 3 Hydra 32 would be more than enought to a Mixed Reef? That would be interesting to see in the testing has a lot of people does not stick to LPS OR SPS, but likely stay on middle. In this situation the Hydras should be mounted Vertically, ou horizontal to the tank?

[@BRStv]

I think that is a fair assumption! I would still mount them horizontally and at the recommended mounting height. A PAR meter will definitely be the right tool to getting this right.

[@reefkeepingandeverythingelse]

Would two Hydra 32s be enough to light a 36 long tank with 20in of height? With like two boomies for SPS and a center one for low light stuff

is it possible to mount the lights 36" above the water? I have a 2000gallon pond and need your recommendation.

We've not tested this fixture 36" above the water line, but you're likely going to lose a ton of par mounting them that high. You may want to look at metal halide fixtures as a potential option.

My question, your video shows 2 different mounting direction. Some of the video shows the lights mounted horizontal (led puck side by side) and some of the video shows the lights mounted vertical (led pucks front and back) why?

[@BRStv]

Since each fixture has two pucks, we were testing out if we could get more even coverage by running them parallel and perpendicular to the length of the tank. Ultimately, not a whole lot of difference with this particular fixture.

Since the 40 breeder is 36" long, you're going to be much better off with the two Primes. You can go with the one 32 if you want, but keep in mind that you're going to have pretty noticeable shadows on the ends of the tank as that light is best for a max area of about 24"

Am i doing something wrong? or do i need to tone the whites down some? I originally had whites at about 21 before the video.

[@BRStv]

No problem mounting it at 12"inches, with the understanding that there is slightly less spread performance expected in those outer edges of the tank. Will that make or break your tank as a whole??..Not at all. When we create our BRS Recommened spectrum we add in the white channel until the tank looks pleasing to our eyes. This is kind of suggestive to what you might consider eye pleasing, but you can always slightly tweak these recommendations to meet your needs.

A 32 gallon biocube is surprisingly pretty darn close to our 60 gallon test tank in terms of dimensions (24" cube vs a roughly 20.5" cube). If you take our BRS recommended settings from this video and reduce them by about 10%, that should get you pretty darn close.

What do you recommend for a 700mm x 700mm tank (500mm height) x3 Hydra 32w or a single 64?

[@BRStv]

Three Hydra 32's would be extreme overkill. Two Hydra 32's or a single 64 will both work fine!

What setting would you recommend for a Ai prime 16hd for sps tank And settings for ai hydra 32hd for an sps tank

[@BRStv]

We still have plans to test the 16HD in the near future, but if it's anything like the AI Prime video we did here, you'll likely need multiple fixtures to get the job done. We'll have more direct setting recommendations after we wrap up the testing for the 16HD. kzbin.info/www/bejne/jYjGZJeLrLaojas

Hello ,for a tank with 35"-25"-15" mostly SPS , what would be the best configuration of hydras ?3 x16 hd or 2 x32 HD. Its a shallow reef tank.

[@BRStv]

I'd suggest two of the 32's and run them from front to back to cover that 25" depth.

Any reason why the ATi Blue Plus bulb is what you try to reproduce as far as spectrum? Having put an LED/T5 hybrid over my tank, of which ATi blue plus was a bulb type, when the T5 bulbs turned on the level of blue in my tank really gave my nostalgia a kick to the nuts, the overall look of the tank was so radically different than what the LEDs can produce at those bluer spectrum that I wished I could have the T5 spread but the LED spectrum with those bulbs.

[@BRStv]

I'd say we use the Blue Plus T5 spectrum more as a baseline comparison to what many reefers have become familiar with in terms of color in their tanks. It's hard to find a T5-only tank that strictly uses Blue Plus bulbs on their own, so rather than try to mimic that spectrum exclusively we do our best to balance a spectrum range with the proven B+ spectrum along with some white, green, red that looks pleasing to the eye. Ultimately, we would like to see more LED manufacturers do this on their own and produce spectrum recommendations that make their lights more "T5-like plug and play", but not everyone does this just yet.

[@Cherub72]

do you know if you can mix 32's and 64's on the app for functionality?

[@jeffcurrier6039]

I have a 40 gallon breeder tank, would you recommend just one 32hd?

[@BRStv]

A hydra 32 is really best for a 24" wide area, so you'd actually be better off with two AI Primes so that you can space them out evenly over the 36" length of the tank. This will be sufficient light for LPS, softies, and a couple of well placed SPS corals.

[@benmorten9577]

Hi just been watching the video and it seem to show the same setting on the single 32hd(lps) as the 4 32hd for the sps tank im a little confused with why they show the same and yet the par is totally different??

[@auryreyes6593]

What did you end up getting?

[@UBWR2022]

Hi BRStv, I have a 48G 3ft lps & softie tank which is more suitable a 32 or 64 in terms of cost wise ?

[@BRStv]

On a 3ft tank you could probably get it done with a single Hydra 64, but I would expect to see some lower numbers in the outer edges. In all honesty, after seeing our 5-Minute Tank Guide series and the 40breeder tank, I would definitely consider 3x- AI Prime 16's for that type of tank goal and that size of system. :)

I'm really struggling with lighting and I have no idea what is best for my 5ft tank 22in high 26wide 60long help would be appreciated thank you it's mostly soft and lps corals.

[@BRStv]

There are a lot of great options to choose from, so I could see being overwhelmed. If I were advising a friend, I would tell them to go with three approx. 90w fixtures for a tank of that size with the goal of softies and LPS corals. The Hydra 32 in this video would certainly fit that bill and has the added benefit of included on-board control, so it's hard to go wrong with it. The Kessil A360X and EcoTech XR15 would be the other two that you might also want to consider.

[@animefan73]

Is running any given channel above 100% significantly detrimental to the longevity of the LED's in said channel?

[@BRStv]

I'm not sure anyone has truly gotten to the bottom of that question. Anecdotally, we've not noticed any reduction in longevity. Granted, we've not done a side by side test and it would take years to get definitive data. By then, the next model would probably be released.

[@goodfela22]

Can you recommend spectrum for 75 gallon? I have two Hydra 32s.

[@BRStv]

You can use the same BRS Recommended spectrum ratio that we developed, then use a PAR meter to turn down that spectrum ratio until it hits your PAR goals for your tank. That way you know you have your specific tank dialed in optimally!

[@anclafn7661]

I was looking for some settings for my 32hd but i only have 15 gallon, there are 4 acros on the top, if i divide the recommended LPS settings through 4 it should be fine or am i wrong?

[@BRStv]

It may get you close, but we'd suggest using a par meter to dial in your lights if your tank is significantly different in size than our test tanks.

[@BRStv]

It will depend on what types of corals you're looking to keep, but assuming a mixed reef like most reefers shoot for, three of the Hydra 32's over your 5 foot long tank will do the trick.

[@EKSforlife]

I have a 150 gallon tank 60 x 24 x 24 how many of these will I need if I’m doing lps and or sps corals?

[@BRStv]

For an SPS system, we used 4 of them on our 4 foot test tank. In other words, 1 light per foot of tank. In your case with a 5 foot tank, we'd suggest 5 of the Hydra 32's. If you're going LPS only, three of the Hydra 32's will do the trick just fine.

If the SPS are lower light SPS and you place them in the center of the tank, you can make that work. Otherwise, you can always consider adding supplemental lighting down the road when you're ready to add SPS.

That's not something that we've tested, but any diffuser is certainly going to decrease the overall light intensity of the fixture.

You're likely going to find that 8" is too close to the water line for optimal spread. That said, if that's your only option, you can make it work. Just know that the center of the tank will have a bit of a hot spot and place corals accordingly. 14" off the water surface is what we usually suggest with these lights.
