Why is this AI Prime is so popular? Is it the low price point? Is it the versatility on tanks from nano to 120gal plus?

[@jonmey4196]

you should do this with the kessil a80 and a160

[@kingfishers79]

I think they are so popular because they are a fully customisable light with decent par ratings and a fair price but most of all they are modular meaning that if like me you start out with a nano and purchase just the one light for softies and lps then upgrade the tank size to something like a reefer 250 and purchase a second light for softies and lps,then when ready to grow a few sticks of SPS buy one or two more as your skills and knowledge grows over the course of a year or more.I also think they are ideal for a mixed reef which I'm sure is probably what most reefers want, I think they are perfect for this purpose but if then wanting to progress into sps dominant reef then I'd probably sell the primes and go for hydras and at which time the sale 3 or 4 primes would be a good chunk of cash towards the upgrade.

Never would have guessed that 2 of these 10" over my 40 breeder @ 100% AB+ spectrum would be putting out 400-500 PAR. Wondering how much glass lids cut the PAR though? I'm going to have to rethink what intensity I really need to set these at now. Thanks for taking the time to collect and provide us with this valuable information. Without a PAR meter, its just a guessing game for us.

[@invaderjoshua6280]

Best budget lighting option I’ve found for a 440g which is 2 240g tanks slapped together making it 8x4x2, is 4 ai primes across the center, and 2 fluval marine 3.0. 1 in the front and 1 back of the ai primes.

how’d that turn out?…

[@Chris2NH]

Thank you for three foot Par numbers! Please do circle back to hybrid fixtures. I just got one for my 40B and would love some real numbers in the t-5 plus some ideas of what LED will add. Kessil too. Right now I guesstimate from your 2 and 4 foot tanks..

[@Glirmi1]

Will watch this tomorrow morning. When i have energy to convert ??? To real measurements. 😛

[@sunnygoold9449]

Awesome - this is so great on useful - I think the best BRS Investigates on lighting so far - the recommendations for tank type are GOLD I am confused though on the LPS tank light spacing. On the outer edges by moving the lights out PAR went from 91 - 94 on the outer edges - like it only gained 3 PAR. But the PAR in the centre dropped from 160 to 124. It seems this is just making the light more uniform by spilling light out of the tank - it would be more sensible to recommend moving out to say 10" where you would have negligible light spill and leaving the reefer with the option of reducing the center output if the reefer wanted. I know this is the format and it usually works but this time, to me, it makes no sense why anyone would do that... ...then you did it for 8 pucks on 4ft SPS tank ;) The 40 breeder setup really demonstrates this perfectly - as they are 10" from the end and that would suggest that is the optimum.

[@johnschuman8910]

Awesome video, thanks!

[@justinw5444]

Would love more info on the customized mounting rack, that looks sweet! Looking for a sleek and adjustable light rack for 6 lights.

[@BRStv]

This is just a mounting rack that is designed for cameras, but with a little of DIY work, has been adapted to mount a reefing light to it.

[@karennation3580]

IIt would be great if you tested retangular tanks that are so common like 12 x 24. I had decide on photon since I only have 4 1/2 inches of clearance the par was much more even since its a big strip light and I can throw out the par at the front and back of tank. I figured if I tuned it way down and sps on top that would work but watching this again and you saying that 12 x 12 cube can be mounted 6 inches I am thinking that with two instead of one that you are using and both mounted towards the end that the spread may make it usable. I really want this versus the photon do you think it will work as well? I can only go with 2 reefbrights so dont think it will work plus to much xtra to buy! . Color pop and growth are most important to me and of course durability and longevity of lights!

[@MrRufusBaker]

Thank you so much for this video.

[@skullring1968]

Can you give an explanation of the moonlight channel. I don't see any noticeable change with it or without.

[@BRStv]

The moonlight channel is mainly for visual affect and doesn't affect par enough to be taken into consideration for our test.

[@austinbabler2165]

I have the 2 16HD’s on a 40 breeder just as you guys show. How deep in the tank was the PAR readings? Was that on the bottom? If it was bottom readings one would be able to assume the PAR readings would be higher up the rock scape?

[@jarich81]

Did they fix this light? I returned mine a couple of months ago. It was much louder than my other older PRIME HD's when on 100%, and was not compatible with them in a cluster since it used Bluetooth LE instead of WIFI.

[@coryr3565]

would love to se some testing on the shallow reef style tanks

[@anthonykastelic217]

Great video! I have a bio cube 32 so I took your recommendation on running my tank at 70%. My question is... was the par values for the 18x18 size tank the values at 6 inches under the water? Like mentioned in the beginning of the video. I’m curious to know as I want to add some euphyllia to the higher parts of my scape.

[@BRStv]

If you go to the 19:01 minute mark, you'll see par data for 6", 12", and 18" below the water line for the 18" cube tank set to 70% intensity.

[@anthonykastelic217]

Ahh thank you!! I appreciate you getting back. Love your videos all of them are sure helpful.

[@markkus1134]

Just got one for my nano looks great

[@sebastiang6179]

Great work guys ;) But isn’t the light pretty „ aggressive“ when u have the UV and Violet channels so high?

[@BRStv]

Anytime you see values over 100% it naturally sets off warnings in our brains, but in this case I wouldn't relate it to something negative. If you look at the spectrum output we achieved in this video versus others like the Maxspect Razor or even a Radion Pro, the spectrum we created for the Prime actually has less representation in that near UV and violet range. It's just the notion that you are "hyperdriving" these channels to levels beyond 100% that makes it feel like it is producing more UV/Violet spectrum ranges, when in reality it's not producing anything more in these ranges than any other light we've tested.

[@Eriktion41208]

I have a 21x21x21 cube mostly LPS. Everyone keeps telling me to use Saxby's or AB+ or Pirates but none of those make full use of the LEDs that this video is suggesting you have to in order to meet PAR goals. They're telling me I'm going to cook my corals having my intensity so high and shorten the life of the LEDs (that part is probably correct). How long of a photoperiod should I keep my settings maxed out liked suggested at @20:43

[@Damien-hr4gz]

Hey Randy, awesome video. Just a few questions though. I have an 18x18 inch with a single puck 16 prime hd. For SPS would you recommend getting another puck? How would you then mount the two pucks on a tank of that size? Would you reduce the output power for both? or a completely different light.

[@Damien-hr4gz]

I'm also finding the single puck causes shadowing on the outsides of any SPS as it is mounted in the centre

[@phatcharoensupnimit7034]

Hi! Big fan of BRSTV from Thailand! Quick question, do prime 16 have disco effect?

I’ve got two prime 16s on a 30 gallon cube due to my coral growth growing over top of everything I’m trying to get more light spread, if my schedule peaks at 80% power during the day does that mean that each light is running 40% power or each light is running 80% power if they are connected together?

[@jennanation6992]

Is it 6 inches that the results are from? if it is then the par will be crazy low at the bottom, so how could you grow lps lower then 12 inches down at the recommended height? Also how high is intensity? Do you have one of these testing videos for a red sea 50 or a lower watt kessil? Also how do you think I would do with two 20 watts on a 24w x 12 deep? I think these may be overpowered for my needs!

BRS! Tell me, at what height from the water and at what distance from each other to put 2 lamps 16 HD, on an aquarium 30x16x14?

[@BRStv]

I would suggest placing each Prime about 8" from center of the fixture to their respective end of the tank. For mounting height, 10" off the water surface would be my pick for this aquarium based on the data that Randy collected for this video.

[@pprince01]

Another OUTSTANDING video! I'm trying to figure out how to extrapolate this to other tank dimensions. For example, I have a Nuvo20 (24x12x12) with LPS and softies. Can I treat that like a 24" cube, raise to 13" and run 100%? Or, do I have to treat it like two 12" cubes and have two lights running at 8" off the water at 25% power each?

[@BRStv]

Using a tank at different dimensions than we tested will be a little bit of a guessing game, but if it were me, I'd use the 24" cube settings if you're going with a softie/LPS tank and use a single fixture. If SPS are more your cup of tea, use the two lights and basically just imagine two 12" cubes sitting side by side.

Is it better to follow this lighting schedule or the lighting schedule from 5 min guide I see this one is more recent and a lot different from the one you guys showed on 5 min guide? Thinking about switching to this one and sticking with it will it bother my corals if I switch?

[@BRStv]

While both will certainly work, I would suggest the spectrum discussed in this investigates video as we went in depth and tested the spectrum with a spectrometer. If you change spectrum, just try to maintain the same intensity (PAR) so that you don't shock the corals with a major change.

[@BRStv]

You can certainly provide too much light to a coral, so you'll want to be careful about running your light at 100% without checking par first. We didn't test a tank with your specific dimensions, but looking at the data and making an educated guess, you'll probably find that somewhere in the 70-85% range will work best for your tank.

@@BRStv I have the same tank dimensions as this person (probably same tank) and I have been running my prime on less than 25%. My coral have slowly been dying and my sps have lost all of their color and polyp extension the past few months. How would you recommend increasing the light on my prime to closer 25%? I don't want to shock my coral but for example if my UV is currently at 16%, how much should I increase it each day along with the other spectrums in order to acclimate my coral to the higher par intensity?

[@BRStv]

13" off the water surface is our recommendation for a 24" x 24" area with the AI Prime. The intensity is what you'll want to consider more with the shorter tank. That said, with a smaller light like the AI Prime, it's going to be hard to over light the tank significantly. I would suggest looking at the data for 6", 12", and 18" below the water surface. The difference between 16" and 18" is going to be small.

I have a Oceanic HQI 29g Biocube. The dimensions are 20" long x 16" deep x 14" high. My light is currently about 12" off the water. I'm wondering where I would fall. Obviously it would be somewhere between the 18" and the 24" cube. I've love some ideas on fine tuning. I don't know if it scales in a linear fashion or not.

[@BRStv]

Given the 20" length, I would suggest starting with the settings for the 18" cube. You'll likely get a little more light spill since your tank isn't a perfect cube, but that'll give you the best results in terms of par and spread.

[@BRStv]

What we usually recommend is 1 hour or ramp up, steady intensity for 8-9 hours, then 1 hour of ramp down. The steady intensity part of the schedule is just the max intensity for that particular light. If you decide to keep two of the lights at a different intensity, you'll just have to program them separately.

Depending on the types of corals that you're going to be keeping, you may need to use quite a few of the Primes to get the necessary coverage. We've not tested spacing on a tank of this size, but the good news is that you can pretty easily replicate our tests by using a par meter. We offer them for rental if you don't want to spend the money to purchase.

I have a 20gl. 24x12... 16inch deep. I only have one AI prime. What should be the optimum set. I’m torn on just keeping that one or getting another.

[@BRStv]

I'd suggest using the settings discussed for the 24" x 24" 60 gallon cube tank. That said, if you want to grow an SPS dominant system, you're probably best off going with two primes to cover the 24" length, then use the 12" cube settings (basically divide your tank in half)

[@joshmitford4450]

Would running the Prime 16 on the 100% suggest settings lower the lifespan of the light? Seems like you’d be over driving some of the channels pretty significantly...

[@lvluxury]

I would think so. Over driving means more heat which equates to less life. The guy that red lines his car everyday wont have that car nearly as long as someone who drives it modestly.

[@randychuah]

I would think the LED chips is capable of withstanding that amount of power. The reason why its over "100%" is due to the available power the control units to light all of the chips, since if one channel goes beyond 100%, other channels will have lower max %

What is the best high for 120l nano tank

[@karennation3580]

What about a 75 gallon 4 ft wide x 18? What is recommended? I am guessing 4. Would 4 hydra 23 facing front to back be overkill? It would be mostly softies, lps and a few sps at the top

[@BRStv]

Four would work out great over a 48" x 18" mixed reef. Four of the Hydra 32's would be overkill for a mixed reef of that size.

[@arnez4208]

Would 1 AI Prime 16HD be good on a 30gal Bowfront aquarium with a support brace across the top of the tank? I'm worried the brace may block the lighting spread.

[@BRStv]

With a center brace, you're likely going to be best off with two lights. The brace is going to cast a shadow in your tank with a single light placed directly above it, unfortunately.

[@Mcappo]

Well I’m looking at this light for a Reefer 170 that is 24 x 20 x 20 is one light still good for this? Will be mainly softies and lps maybe light sps down the road. Thanks for this vids!

[@BRStv]

Definitely a solid light for LPS and Softies. Lower light SPS towards the very top of the rockwork shouldn't be a major issue.

[@Mcappo]

@@BRStv Awesome thanks!

[@gadamwoll]

Waiting on the Hydra 32 for 75gal set up.

[@jjmccloud]

Just 1?

[@satjosh101]

Do you guys have a suggested setting for the 18 inch cube mixed tank?? I saw the setting for non sps but if I wanted to mix it up and have sps on the top suggested settings??

[@BRStv]

If you set the BRS recommended settings to about 90%, you'd probably be really close to ideal mixed reef numbers.

[@lukefham7138]

You measured the light 8-10” height for the 12x12 and 18x18 but those pars that measured, how deep was it in the tank ?

[@BRStv]

For all of the mounting height tests, we were looking at par 6" below the water surface.

[@MiniCookiez]

Should I keep just one or have two AI prime 16hd for my 20 gallons long?

[@BRStv]

Two Primes would be a better choice for a 30" long aquarium like a 20 long. Perfect lighting solution for a mixed reef 🙂

[@civicekhatch9]

Hi BRS what are the percentage of the intensity were using to get these par ??

[@BRStv]

For the height tests, 100%. For the individual tank tests, Randy discusses the settings for each individual setup in the video. Each tank from the 12" cube to the 120 gallon tank are going to use slightly different settings.

[@crunchtimerell1683]

Will 1 *AI PRIME 16 HD* work on the *JBJ 45* which is 27” long

[@CP-vq9ng]

Nice informative video but how did u get such high numbers my uv and violet go up to 133 and royal blue and blue 105 only?

[@BRStv]

There was a recent firmware update which limits how high you can overdrive some of the channels. Here's what I would expect to find from the changes. 1) Negligible to nearly zero change to spectrum output compared to our BRS recommended settings. (All of the same spectrum ranges are still there. Perhaps the numbers in the app have changed, but fundamentally nothing has changed in terms of available spectrum.) 2) Slight difference in PAR output . I can see some slight degradation to overall PAR output, but I wouldn't expect it to be linear to the max % you can drive each channel. (As an example, if I once was able to drive the blue channel to 150%, but now I can only drive it to 135% ... I would not expect that my overall PAR output would be a full 15% less, especially if you try to extrapolate that across 4 other channels for a 75% total loss in PAR output.) If that were the case the light would be nearly unusable and I just don't see that happening.

[@Thrice1337]

I currently own the generation before the 16HD. The version that does not have the moonlight. I think it’s the AI Prime HD+? In regards to spectrum for 12x12 SPS... Should I just maximize the UV, V, RY, & B? Then mimic the green, red and white settings? (119, 116, 122, 111, 9, 9, 59)

[@BRStv]

You got it :)

[@Thrice1337]

@@BRStv thank you for the quick reply!

[@buffalosoldat]

Hey @Bulk Reef Supply, Are two Prime 16HD with power of 55W each giving more PAR than Hydra 32HD 95W?

[@Evan-mh7it]

Where were the par measures taken on the 60g cube? The bottom, middle or what, I'm worried the depth of the tank is killing my par?

[@Evan-mh7it]

6in deep in tank....

[@BRStv]

Par was taken at 6", 12", and 18" below the water surface. Check out 20:43 for example.

[@Chelmon_lol]

Let’s be honest, the AI prime 16 hd is never cheap in itself, but cheap in the long run I have to agree with that

[@Jp-gc6bh]

I love how I don’t need to rent a par meter.

[@achunkyduck9740]

For the initial readings for the 18inch cube at 9:18 is that on all max settings? Im confused what settings u used for that

[@BRStv]

That's correct

[@sagarsalvi1017]

I have a 12" flex arm over a 12" x 12" nano tank. Can i still go for the recommended 8" settings for LPS or make some adjustments for 12" mount height?

[@BRStv]

Mounting the light a few inches higher, you'll have to increase the intensity a bit to get the same results. Just increase each channel in equal ratios. Other than that, you'll just have a little more light spill out of the tank.

[@alexmillan4254]

Have these setting been used in a actual tank filled with corals and seen if corals react better to this lighting

[@BRStv]

We've got all sorts of different lighting on the tanks around the BRS office. Hard to compare directly as there are a ton of other factors like types of corals and the skill of the individual that is taking care of their own tank 🙂

[@sa7el]

The par readings are at the bottom of the tank?! Or how high exactly in the tank?!

[@BRStv]

For the mounting height test, the par readings were taken 6" below the water surface. For the spectrum setting tests, the par readings were taken at 6", 12", and 18" below the water surface (where applicable). That is listed on the left hand side of the screen when Randy gets to that part of the video.
