Kessil/Reef Brite runtime

[Cari]

Hey everyone, Looking for some help with schedule for Reef Brite xho actinics added to Kessil AP9x.

I just mounted my 2 Kessil AP9x in Reef Brite xho dual fixture. I’m starting the RB dimmed down to 25%. I turned it on 100% and took some par readings, it pumps out some par so turned it down. The Kessils run a schedule from 8am to 8pm. They peak at 50% intensity for 4 hours.

The purpose for the RB is to give the corals the benefit of actinic and me the coral color pop.

I’m looking for RB schedules. Years ago, when I ran MH/T5 actinics, I ran them a little before, during and after the MH schedule.

Let me know what you’ve been doing! Thanks!

I have four a360x lights on a Reefbrite xho fixture. I only run the Reefbrite at peak intensity hours. It is at 100% during that time. The Kessil’s ramp up till the Reefbrite is on, then go down to 30% on full white. After the Reefbrite fixture turns off, the Kessils ramp back up then slowly down again.

Basically my graph for the Kessils looks like an “ M “.

12 hour total, 6 hour peak.

What Par are you getting with your ap9x's on 50 percent?

My tank is 90 gallon, so 24” deep. The lights are about 11” above the water line. Attached is a pic of readings with Kessils only. With the Reef Brites on 100%, it added about 30 par to the bottom of the tank. I’m going to take additional readings tomorrow.
