Ok so I've noticed something pretty big since I've been using these hydras. Since lowering the uv about a year ago, most of my red corals have turned orange. My parameters are spot on and have only had this issue with LEDs.
After tons n tons of online reading it seems to be an LED lighting issue. I've power up my uv from 15 to 30 and am going to keep observations and see. If the corals redden up, I'm gonna go a bit higher with em. I originally turned the uv down due to SPS browning as a result of the higher uv. Kind of a sun block effect. We shall see how the Reds go w the new settings
Anyone else noticing this?!
Yes i had the same issue - I actually dropped the violet setting to 40% increased my UV to 60 for 3hrs and in the process of increasing my white to 70%
I have also shut off my red and have my green on @ 15 for 3 hrs
