Torch coral dying.

[bkushy]

Can someone please give some advice on this. All of my parameters seem good now. Salinity was low for a bit due to an uncalibrated refractometer. I switched from 6 X t5ho lighting over to two ai sol blue fixtures. I have slowly turned the fixtures up starting at 35 percent on all three channels to 65 w and 55 for each blue. I don't know if it needs more light. Less light. Or if it is altogether unrelated. Everything else in my tank is doing good except for snails and a tube worm which are being harassed by a black brittle star I can't catch. Any advice would be awesome.

I suspect it's your lighting. How long have you had the lights and how much time between jumps in lighting intensity? Also how high for each jump.

Since xmas. Not sure how much time in between jumps. Everything else looks good so I figured must be ok. My t5ho setup was much brighter which I expected but was afraid there wasn't enough light.

The t5 may have seemed brighter but LEDs give off more direct light. You should slowly increase the lighting when acclimating, I do 3-5% a week
