I'm wondering this myself
The reef box LEDs on either side are only running the white light (blues are switched off) so I guess running at half power.
The centre hydroponics light seems the problem. Hygro under that constantly has issues. Unfortunately the light doesn't have a dimmer. The only saving grace is its mainly reds that lose power with depth and tank is 2 and a half feet deep.
Looking at seeing if I can run a dimmer switch or a timer on it I think. It seems way more powerful than I thought (but not sure). Need a PAR meter...
