I don't have ai Primes but what are your settings? And do you have a par meter?

Yes i have a par meter it's luke 160 to 170 at the top

Need more white to get the PAR higher with only 4 Primes. I’m running 2 Hydra64’s and an Orphek OR120 on my 75. You can try turning the whites up, if it’s too white, ad a blue or a UV 48” bar of some sort.

I'm not a Prime user either.

Looks like half of the channels are basically off. You are probably lowering the lifespan of the LEDs and risking melting the lenses with % that high on the UV.

Raising the cool white would likely help a lot. I would raise those channels a bit for about 6 hours a day for the SPS photosynthesis. After that, if you like viewing the tank with more blue, adjust the schedule for evening viewing.

You are going to burn out your lenses in no time with those settings

Based on this video, I would think that 4 16HDs on a 4' tank would be plenty.

Seems like you have them cranked into overdrive too.

Strange.

How high above the tank are they and how spread out from each other and the edge of the tank?

How high above the waterline are your lights?

I was just going to say UV is going to burn your lenses. There was just a thread this morning they just had to replace their lenses cuz they got burned out. It's a bad design lower your UVs

Do you think 2 more primes would help

Alright thanks

Using 12 in goose necks

Yes. For sure. That would be the equivalent (ish) to 3 of the Hydra 32’s. 6 Primes should get you there, and an LED bar will pull slack. Like others said, your settings are going to fry lenses so keep some on hand.

Your printscreen looks like Prime 16, not 16 HD. Are you sure they are 16 HD ?

I had 4 x AI Prime 16 HD on my 75 gallons, 48 inches tank and I had 300 par at the top. Light intensity was about 85%. 21 inches deep aquarium and lights about 9 inches above the water.

@JCM0521

Have you downloaded any schedules from AI??

I use the Saxby on my 40GB and my 13.5 Fluval Evo.

You should be just fine with what you have, but as others have said...you have UVs and Blues cranked 1000% max, with no white.

Go to the AI website and download some schedules. This will help you immensely. They have plenty of options from reefers all over the world

Also just like @nereefpat said.. you need more white...SPS tanks can not live as a windex tank like LPS do, you need more natural bright sun light running through the day, not blues and UVs at 1000000%


For instance...
