8 on the day and 10 on actinic, you could go as low as 7 but any less than that is not long enough and unnatural

How does that 22k compare to the blue+? I have thought about giving them a shot

Gives it a much nicer deep blue then IMO the fake blue of the at I ACTINIC. But I run both at I actinic and reefspec22k gives it a really nice look not really blue blue. But a crisp look and you can see all the coral colors perfectly with out that flood of blue.

--- 16 royal blue epistar LEDs: 8 AM - 9 PM
--- 4 ATI T5s (2 coral plus, 1 blue plus, 1 purple plus): 10 AM - 7 PM
--- 14 royal blue LEDs (mix of cree & luxeon): 1130 AM - 530 PM



This is an all acropora, millipora, stylophora tank. I have changed the lighting schedule lately thinking that might be why things look a little bleached. And I am thinking about replacing the purple plus with another blue plus - too much pink.


--- 16 royal blue epistar LEDs: 8 AM - 9 PM
--- 4 ATI T5s (2 coral plus, 1 blue plus, 1 purple plus): 1030 AM - 630 PM
--- 14 royal blue LEDs (mix of cree & luxeon): 1200 AM - 500 PM

It would be nice to know what kind of tanks people are running with these lighting cycles.

My tank from my APEX:

48" Reefbrit LED blue
If Time 09:00 to 22:30 Then ON

Actinics: Blue+ and Purple +
If Time 11:00 to 21:30 Then ON

Daylights: 3x Blue + and 1x Coral+

If Time 13:30 to 19:00 Then ON

I have been messing with it a lot trying to get the best colors. My corals seem a little bleached and my LPS are more colorful in the shade. My tank is an SPS dominate 90g with a 6x54 ATI sunpower.
