SPS coloration (Ohio 230 Reef)

[tjsailosullivan]

Was looking for some thoughts concerning coloration. I have been keeping this reef tank for some time now (Almost 2 years). Some of my SPS are growing great and have great coloration. However there are a few SPS corals that have expelled the green color over time (1 year) and kept its reds and blue tips. I know there are probably 50 different possible senerios (Lighting, Feeding, minerals etc..) but was curious to see what some of the thoughts are. I just find it strange that different corals do great and keep the green but there are a few that I cant seem to bring them back. (E.g. Red planet) I also noticed that the ones that have lost the green are the ones that tend to have slow or no growth. I do have a very low nutrient system and going to take the great leap of removing my carbon and GFO since I do have a good size refugium. Will have see what happens. Anyways looking for some other thoughts.

what kind of lighting do you have?

Running a combo of radion G3 pros (50%) T5s and BMLed strip. But have had the same problem when I was running MH?

what Kelvin setting are you using? I have really good greens on those species that are appropriately green but have a ATI blue + T5s and 12K MH which seems to be a good overall combo for me. What MH K were you using before?

is there any trend on coloration based on placement? For instance are the ones higher not as green? Looks like you have green slimers on top of each of your stacks. Hard to tell from your videos which ones are green but if your top corals are green slimers, they looked washed out to me.

I tend to be somewhere around the 18-20K range

There is a little trend on my green coloration at the higher levels of the tank. The video was taken with the IPhone with the blues on so a lot of the colors are kinda washed out from the camera. I have a green monti at the lower level that seems to be a little darker. My greens always seem to go from a dark green to a light neon yellow color.

My photos come out a little better for my slimer.

Which corals lost their green? Some of them, like red planet, do exactly that when they have ideal parameters and conditions. Do you have any names or anything?

FWIW - if you are looking for a coral that keeps a nice red/green contrast, then Atlantis Christmas Mirabilis is a good one.
