I just installed LEDs over my 90 gallon and I have a few questions. #1 when controlling your LEDs with the apex lite are you ramping them up and down to mimic sunrise and sunset? #2 since putting optics on your LEDs have you checked for par reading on your sandbed? I have my LEDs about 8-9" off of the waterline without optics and debating if I should put 80° optics but worried about the disco affect.
Congrats on your Leds.
Let me say that I do not have a dimmer on any of my Leds. If I did it again, I would put a dimmer on my Cool whites and Neutral whites at least (and I still may do this in future)
I have 8 sets of lights: All cree
One strip of Neutral White 12 leds
Two strips of Cool White 24 leds
Four strips of Royal Blue 56 leds
One Strip of BLue 14 leds
Not exact on the times but this is close:
I ramp up 2 sets of blue first 9:00am - 9:00PM (80 degree optics)
then another 2 blues 10:00- 9:30PM (80 degree optics)
then 2 cool whites 11:00-6:30PM (80 degree optics)
then the Blues 11-10PM (60 degree optics)
then High Noon Neutral Whites 12:00-4:00 (60 degree optics)
SO..... Five of my plugs on my APEX are just for lighting
1. AM i ramping? I guess so in my own way
2. Prior, in this thread there are par reading in one of the pics. ranged from sandbed 100-550 I believe
Do you need optics? Not sure. Too many factors to consider. Check your par on sand and top.
My zoas, torch, hammer, shrooms, acans, candycane, etc grow with 100 par.
FIY 80 degree optics shouldnt make a shadow effect. Also, there are factors here too
Good Luck
