Monti cap browning help

[Fishinbob]

Hey all have a Monti cap that's browning out got it over a month ago and it was somewhat brown when is got it then after a week It started to green up!! Here's some tank info

10gallon tank
Lighting
14 Cree 3w LEDs 8" from water(7 rb, 5 cw, 2 b)
Temp. 77.9
Ph 8.1
Nitrates .25
Phos. .3
Cal. 450
Alk. 9.8 dkh
Mag. 1250

I know my phosphates are high I am running poly filter and some BRS gfo... I have a slight red cyano problem but it's slowly receding with my weekly water changes about 2-3 gallons... What's weird is seemed like it was doing better when the Phos was higher other than that nothing has changed!! I'll post a before and after pic once I get home
Before 1.5 weeks ago

Now it's almost completly brown

That doesnt look like a monti to me (on my phone). Make sure you alk is steady with the addition of gfo

That is not a Montipora. It is a Pachyseris but likes the same general conditions as the Montis. Do you know what the conditions were that it was growing under before you got it?

Thank you Richard much appreciated on the ID!!! I looked like crazy trying to find it son I wouldn't look stupid! Actually yes, I got it from a LFS and prodded a bit to get some info
Tank is 60 breeder
4 54w t5's 16-20" from coral
Ph is roughly 8.2
Nitrates around 10 he said
Phos. .30 I believe
Temp 78ish
Alk I don't know
Cal he said 420is
Mag was around 1300

In the store it was brownish with slight green... Went into my tank after a acclimation and dip and colored up in a week... Held color for about 3 weeks then started to fade just this week! Just so I dot leave anything out I keep a sg of 1.025 and photoperiod of 6 hrs right now to help combat cyano. I know things don't happen over night I was late on a pwc by a day just want to know what direction I should look thanks guys

Well it has started to bleech I checked my timer and well I guess I pushed in some pins by mistake looks like it has Been running 10-12 hrs for 3 days or so my frogspawn has been closed up too! I moved the lights up to about 10" or 12" above water line moved the pachyseris down a bit and shaded the frogspawn with some eggcrate seems Light light is the only variable that has changed. my Phos is a bit high mag a bit low but within tolerance but I don't have a dimmer on the 14 crees so max light might be a tad much especially for so long... Please any input would greatly be appreciates!!
