How long has this schedule been running? I don't use cloud feature but understand that it just reduces intensity a little. To that end, why is there a massive dip in the middle of the day?
I run this on my 425 XL with two ReefLed 90's. I figured that it represents the sun's cycle throughout the day but couldn't say how effective it is. Sinularia, mushrooms and anemone all happy but leather and Zoas show little growth. The Zoas aren't stretched either although I think it's more about chemical warfare!
