Help me choosing a lighting schedule

[Zuluuz]

I’ve been running 14k all day at 300 par for the past few months but the fluorescents on my acros are beginning to fade. I’m figuring that the whites are on too long so help me choose which makes more sense to experienced sps keepers in terms of white channels. Schedule A or schedule B

I’m running Reefbreeders meridians with edge bars

Previous schedule was all channels at the same percentage all day for 12 hours. Growth was good but colors are fading

Like this?
Day is full sun until noon, I have the whites darken up early so it's lots of Blues in the afternoon. It's a 3-hour ramp up with a 6 hour day and a 3-hour ramp down.

IME, 8hrs is plenty of time at full intensity for a photoperiod anything more is overkill. I’m not sure if the corals will even photosynthesize that long.

There might be other factors at play causing them to fade as well. I’m assuming all other levels are pretty stable if you’re jumping to lighting first?

Sorry I joined the party late. I like the first schedule the best. I just think the overall settings are down way too low for you to achieve your desired 300 par. I I'm chiming in because I am seeing a little bit of color fade in some of my acros as well. I have the new meridians and a t5 hybrid setup. A recent ICP test and a confirmation with a home test showed I had low potassium, in the 350's. I'm slowly adding some Red Sea Colors B to get my levels up. Check your potassium this might be the culprit.

You're really not going to be able to tell too much from my Meridian schedule, I run it this way because I have my t5s come on first thing and then they reduce throughout the entire day. The way I have this set up is really more for some fill light, and a little extra punch at my light peak in the afternoon. ( Really only 3 hours). In reality it's mostly for achieving the nicest visual blend.

This picture is pretty much a true to life photo of what the aquarium looks like later on in the schedule probably around 7:00 p.m.
