So it's been a few weeks and I've been adjusting trying to clear up the brown sand bed which came when I installed the 52s. No3 and Phos or extremely low (no change to what it was before). I've been. Following this thread and posted early on. After seeing what others have, I am going to drop R&G down and lower my whites. Here is what I just set mine to:
W-30% for 7 hours with 1.5 ramp up/dn on each side
R-11am-9pm ramping up to 8% at 4pm and back down
G- same as Red
RB- 70% from 11am-6:30pm with 2 hour ramp on each side
DB - Same as RB
V- 40% from 11am-6pm with 2 hour ramp on both sides
UV-20% from 1-7pm with 2 hour ramp on each side.
I will monitor the sand bed and corals. Corals appear good now, but perhaps they'll get even better growth.
