Nice tank:)
I also have A360we’s and t5’s (for 3 years). I’m really speaking from experience. You are right that the corals you have recieved are far from how they should look like. I don’t want to take that from you, and 100% agree.
but:)
I’ve experimented with the whole ATI bulb range and Kessil color (lol) range over the years. What I’m trying to say here is that purple+ bulbs will bring out the brown color even more a lot, so it is adding to the trouble a lot And so will the Kessils above 30% color. Even if that was a totally healthy frag.
I wish I had a camera that I could shoot pictures of my tank for you with the Kessils on different color settings & with different t5 bulbs, for you to see what I’m talking about. But my camera won’t go above 8000k, and that’s still in the corals look brown under it range. I can change the colors of my corals instantly from decent to everything is brown, just by swapping out bulbs or twisting the kessil color knob.
This is the best I can do:
white light:
kessils 100% color:
kessils 30% color:
t5 only (actinic and blue+):
shots were taken in a 30s window.
now pay attention to the red plating monti, for example. It went from ugly brown to super cool red/pink just by recieving different spectrum. Also note the added brown tint between the 30% and 100% kessil color pictures. Once again, I’m not saying lighting is your only problem here, what I’m saying that purple plus bulbs and high color settings on the kessil aren’t helping it.
