Dimming LEDs with an Apex

[jimsflies]

As an update to this thread, here is a link to the DIY connector cable I made:

My initial settings on the Apex look like this:

Profile Setup:

Profile Name: RampUP
Control Type: Ramp
Ramp Profile Setup:
Ramp Time (minutes): 120
Initial Intensity: 0
End Intensity: 20

Profile Name: RampDWN
Control Type: Ramp
Ramp Profile Setup:
Ramp Time (minutes): 120
Initial Intensity: 20
End Intensity: 0

Profile Name: RampUP-2
Control Type: Ramp
Ramp Profile Setup:
Ramp Time (minutes): 60
Initial Intensity: 0
End Intensity: 10

Profile Name: RampUP-3
Control Type: Ramp
Ramp Profile Setup:
Ramp Time (minutes): 120
Initial Intensity: 10
End Intensity: 20

Virtual Outlet Setup-

Outlet Name: Whites_Dim
Control Type: Advanced
Icon: Light A
Advanced Setup:
Set OFF
If Time 09:00 to 11:00 Then RampUP-2
If Time 11:00 to 19:00 Then RampUP-3
If Time 19:00 to 22:00 Then RampDWN


Outlet Name: Blues_Dim
Control Type: Advanced
Icon: Light B
Advanced Setup:
Set OFF
If Time 06:00 to 22:00 Then RampUP
If Time 22:00 to 23:59 Then RampDWN

So this program turns on the blues at 6 am, ramps them to 20% by 8 am. Then the whites come on at 9 am and ramp to 10% by 10 am. Then at 11 am, the whites ramp from 10 to 20% by 1 pm. From 1pm to 7pm, blues and whites are both at 20%. At 7pm whites dim from 20% to 0% by 9 pm. Then at 10 pm, blues dim from 20% to 0% at midnight.

I will increase the intensity slowly over the next few weeks to acclimate my corals. They are used to an old halide so I think they will require a bit longer acclimation period. Corals are already responding well to the increased light. Polyp extension yesterday was the best it has been in awhile.
