I have a 55G tank that has been up for almost 8 months and I didn't start adding coral until the 5 month mark
I have 2 AI Vega's 10' off the surface and around 47X turnover in the tank...I used BRS reef saver rock and am running a 20G sump with reef octopus NWB110
I have mostly LPS and a couple SPS pieces...SPS are 3 monti's, 1 tri color birdsnest, 1 digitata, 1 table acro, 1 ora borealis and a green birdsnest
I have multiple LPS expelling zoox and bleaching, my table acro/borealis and green birdsnest are brown (the ora borealis and acro are growing however). My red monti's are very pale and my zoas are only growing down
everything was doing fine up until a month ago when I started dosing potassium nitrate, I got my nitrate level up to .50 then my green birdsnest browned/bleached and now it seems everything is going down hill...lps not as open, some zoas not opening and can't figure out what is causing it
I thought I may have had a huge spike in P04 and did 9 10% WC's over a 2 week period but algae continues to grow on the glass...had cyano in sump and it has decreased by 85%
my lighting schedule has a 4 hour ramp and 5 hour max intensity at 29 white and 58 blue
parameters
ALK 8.8
CAl 420
Mag 1300
PH 7.9
Sal 1.025
Temp 79
N03 .50
P04 with Hannah 0.00 (have a little algae on glass)
MY alk has been stable for months, never swinging more than .3...I haven't messed with lighting or touched/moved any corals
I don't know what to do...thought about lowering light but browning in sps tells me not enough light or too many nutrients which I don't think I have. I have tested RODI and holding containers all reading 0.00 P04
