I have had my 28 jbj for several years. It comes with stock 89 watts LEDs. They are not dimmable. I have great growth but never have had good color. Always felt like LEDs were too bright and always bleaches several corals.
So today I decided to disconnect some of the stock white LEDs in my hood. Tank looks 100% better. Not too white like before. Perfect color combo with the royal blues. Colors seem to pop more with less whites. I have lowered the LEDs to 63 watts.
I'm just wondering if it is okay to cut back lighting in tank. I know you have to raise LEDs intensity slowly but is it the same when lowering it. Does it have to be done a certain way. Is 63 watts okay for my size tank. It's 45 watts whites(15X3) and 18 watts blues(6X3)

With the lower led intensity. Could corals regain colors.

The only issue with disconnect some LEDs is that the driver for the LEDs is rated to run a certain amount of voltage to the LEDs. Now that you've taken some out more voltage will be forwarded to the remaining LEDs causing them to possibly run brighter and shorten their life span. If it works it works but I am not sure if it work very long.

Do the LEDs have optics? ( I have never seen the jbj led hood before)
Possibly try reconfiguring, your saying they 3 LEDs right? Maybe purchase and install more blues or royal blues.
