Favia losing color

[PR_nano]

Bought a Favia frag early December as first coral and it has been losing color. So far I moved it to sand bed, away from direct light and started feeding roids. Anything else I could do or waited it out to see if it makes it? Tonight I moved it a bit away from the rock so it should get a bit more light/flow.

How long has the tank been setup? What are your parameters? #reefsquad

Moderate light and water flow. Seems you are heavy on blue- add about 15% white.
Feed 2x weekly.
What is your salinity and ph?
Salinity range 1.025-1.026 best and ph range 8.0-8.2

Tank was setup early Nov.
3 days ago Alk was at 11.5, Cal 490, Mag 1290, PH 8.0. I just measure PO4 at 0 and salinity at 1.025.
I changed the flow from crest to lagoon this past weekend and Kessil were set on scheduled roughly 2 weeks ago. Max intensity I believe is at 45% need verify. Before that I had it set static (8 hours), no ramp up or down. I will pull the light schedule that's something I'm struggling with.

Most likely from intense lighting, high alk and low nutrients. I wouldn't worry about ph, chasing certain numbers does no good. If your going to run high alk you should have some nutrients in the water, typically 10ppm nitrate, 0.03-0.07 phosphate. Those are examples as their is no magic number. I would not start changing your light schedule, start with one thing and make changes slowly. Adding more light will not help this situation IMO

Thanks a lot guys, I will slightly increase feeding (roids 2* a week but small amount) and make bigger water change.

My light schedule is 10:00 color 0 intensity 10, @12 10/20 @2 35/45 @4 50/35 @6 25/25. Any recommendations on it or should I post in the light thread?

All good advice

I have like 25 Favia's in my tank ,, lighting is a big deal ,, my Par numbers on my sand bed are in the 125 range and I have problems with some of the Favia's ,, I have them placed close to the front and side glass in my tank ,, some grow good all the way around whatever I have them mounted to,, some grow good towards the glass but not so good towards the back of the frag ,, back towards the center of the tank. I got a couple of new ones in the other day ,, one was faded a pretty good bit ,, I have that one pretty shaded, close to being under a rock but not all the way ,, the is not as faded as much ,, I put that one right in the corner of my tank ,, its the lowest Par area of my tank and still be out in the open ,, I feed them right at once a week with Reef Roids ,, sometimes I have to skip a week ,, depends on what my Nitrate number is at

I´ve fed my favias both reef roids and pellets and I find mine like pellets more.

I feed EasyLPS every two days.

I think alk is to high and nutrient to low for it and a lot of LPS. Do you dose ALK? What salt do you use?
Light is a tough one and take time to get right. Took me a long time to get the sweet spot on my LEDS. But to help guide you with a ramp up and down schedule, shoot for having your LEDs peak power for about 6 hours a day. For example: if you max out at 50%, ramp up to 50% for a few hours and leave it around 50% for about 6 hours then ramp back down. Now how much power will be trial and error. On my tank my max power is 70% on my blues. My whites never go over 20%. But 6 hours my blue channel is 68-70% power/intensity (I have reefbreeder photon v2s)
