Acros and lighting

[dmh41532]

I have a 24 cube with a single ai prime over it. Im
Not sure if what I have it set at will be enough. I was given some bad advise to turn the lights up to 50 percent for the white and 100 for the blues and uv…lost a lot of coral even with an adjustment period.

Hmmm i dont have the fancy settings on my kessil but i usually do either 75 blues 25 whites or just straight 50/50. but I shall leave this as a bump so if someone has the AI prime they can help more!

I would turn the UV up to 80% as well. Turning the blue channels up to 100% would be a good idea if you do a 60 day adaptation period. You get more PAR from white light than from blue and 50% white is likely what hurt your coral. The schedule looks good to me.

This is my AI schedule for comparison:

I would NOT turn up the uv to 80%.

That will/could melt your lense.

However, I would get it off zero. Maybe start at 20%

I run my prime at 75-80% for the blues and uv, 5-10% green, 0 red, and whites around 15%

This is over a 15g Waterbox with the gooseneck mount

I have a 15 gallon tank, 12" depth, its a softie tank just mushrooms and zoa's, I have my prime at 70%. I don't think your corals have died due to this light is too strong, its not that strong actually.

I don't believe one prime would be strong enough for sps with 24" depth. Agree with above 2 would be better.

I have actually found it to be the blue providing more par. I have a different light though for my main tank. I do have a blade on another tank that I just took one of the presets and liked the par it provided. If i turned my blues up to 80% I would cook my tank.

Forgot to add…this is one prime over a tank 10g less, and these are my settings for gonipora and zoa.

The prime is a weak light. Not uncommon for people to overdrive the channels and have a few at 120%

And melt lenses.

Mine melted a lens already and I don’t even push it that far

Interesting. I have measured PAR under all the channels individually and together. At work now but can post numbers later. I have 6 AI hydra 32 HD over this tank and a couple of hydra 64 over another tank. Always funny to find different results from similar lighting.

I was just getting ready to say that about the uv. The store that sold me the unit said to not run the uv above 30 because it will melt the lenses. The store I tend to buy the sps frags from said uv irritates sps and they recommend against uv.

I have the same light over a Waterbox 35.2. I've got my lights turned up to around 110% for blues and 65% UV running a modified Zaxby schedule which I turned up a little. I believe the whites are around 50% as well. I am only getting around 250-300 PAR 4" under my water line and 150 PAR at the bottom of the tank directly under the light. The back corners are only getting around 65 PAR. My tank is roughly 18" deep. I too am concerned about melting lenses and don't want to turn it up anymore, so I ordered a Noop K7 Pro III which is a way more powerful light for the money. The Prime 16HD is good for softies and lower light SPS but I don't see it growing Acros very well unless they are centered under the light at the very top or you buy a second one. Right now mine is set about 8" over the water.

My old 18" nano cube running 2 16's.
First 4 channels 100% the rest 50%. I melted a few lens at above 100% but a new lens is only $5.
These are the lights that convinced me to go 100% leds from halides after 30+.
10" off the surface.

I do have the acros directly under the light, maybe 5 inches under the water. All I can say is I slowly raised the whites to 50% and I lost a
Lot of coral. Even some acros. I’m just trying to find that sweet spot. Some people are telling me to set all channels at 100 %…that seems excessive to me

Well depending on your acros, they may be just what they need. I haven't put any in my tank yet because i know I'm not going to get the amount of light I need for acros unless I use two. I do have a birdsnest, digitata, and an anacropora that seem to do well with my current set up, but they also don't need but a couple hundred par. What are your water parameters like?
