After hours of endless research I'm at a complete loss as to what could be going on with my tank so I'm seeking help. A little background, the tank is a Fluval evo 13.5 that's been up since Jan 18th. I'm running an AI Prime HD, Sicce 1.0 return with RFG, Hydor Koralia, and a InTank basket with just filter floss. The tank has always used Red Sea Coral Pro salt with 0 TDS water, but i'm slowly transitioning it to Red Sea blue bucket. Two fish, a yellow coris wrasse, and a cherub angel.
Now my issue is I feel like most of my corals are hanging on for dear life at this point. I have two acan's that are almost completely receded 90% of the time, a candy cane coral that's receded, a chalice that was one of my first corals in the tank has lost a bunch of tissue recently, another that was growing like a weed has suddenly stopped and started to recede. A frag of bubblegum digi that looked awesome and was growing like crazy suddenly stopped and lost almost all of it's polyps. It seems like things grow then one day decide to die. The only things that seem to be enjoying the tank are my two torches and frogspawn (both of which are not touching any other corals) and several clusters of zoa's. I even recently added a kenya tree and in about a week it's basically melted away. I'm out of ideas at this point so any help would be greatly appreciated.
Parameters as of about an hour ago:
Salinity: 34.9
Temp: 80
pH: 8.1
Alk: 9.6
Ca: 460
Nitrates: 5
Phos: (I hate the Hanna checker) somewhere between .02 & .05. I tested 3x.
Other than that I dose about 2mL of Red Sea AB+ every day, and Vibrant about once a week.
