SPS Placement

[BestMomEver]

I have a relatively new 60 cube (24x24x24) and have installed a Radion XR15 Gen 4. The Gen 4 is approximately 8 inches above the water and I am running the Coral Lab AB+ program at 50%. The highest point of my live rock is about 10 inches from the surface of the water and my baby acros are on the highest part of the rocks. I want to make sure that my few baby acro frags are receiving the appropriate light for good growth but am not sure if they are high enough or the light intensity high enough (or too low or just right). Can you guys help? What are ya'll running?

Generally you should acclimate new frags to the lighting. Since you don't know the exact settings of where they came from and likely you didn't match your tank parameters to the same from the source water, let them acclimate slowly starting down low then moving them up higher slowly over time. If you have done that, just judge by observance over time. Are they growing? Do they show good polyp extension? If not, something is outta whack and it could be lighting or it could be a multitude of other causes.

Get a par meter or read lux with your phone. For T5 I would try and settle with 400 par. They liked that.

You should be fine. I have a similar set up for my acro grow out/frag tank. I'm using XR15 Gen 4 using the diffusers running 65% intensity/AB+ and I have acros that are 10-16in from the light. Not sure if it is the diffuser but I'm sure the Acro's could take more intensity. No issues with bleaching or colors fading. This includes frags that came over from T5/Halide or other LED setups.

On my tank the xr 15 is 16 inches off the water with a difusser in and 12” in tank at infesting 65% and I grow and keep good color on sand bed
