Hello, I have a 100 gallon Innovative Marine EXT100, and I'm losing corals. For lighting, I'm using two AI 32HDs. I run a protein skimmer, refugium (which is not at all growing my chaeto), a Carbon/GFO reactor plumbed into the manifold, and a UV sterilizer.
I started this tank in November 2020, and cycled it with media from a previously established tank. I've gone through Cyano, dinos, etc, and everyone has been fine. Three weeks ago I went away for a weekend trip (left Friday, returned Sunday), and had just replaced the carbon and GFO. When I got back, I noticed that 1 hammer frag appeared to have *i think* brown jelly. I also noticed my scoly was receding suddenly, as well as my plate coral. All other corals (torches, other hammers, frogspawn, acans, duncan, leathers) were fine. I performed a 10% water change a few days later.
Now over those last 3 weeks, I have lost the scoly, two plate corals, 1 torch (that is bailing now), 1 tachy that is also receding, and 3 heads on my 8 head hammer.
I have no idea what's going on. Here are my parameters.
Salinity: 35
Temp: 77.5
Ammonia: 0
Nitrite: 0
Nitrate: 20
Phosphate: 0.2 (this has been a problem for me... I'm currently dosing NoPOx to get this down.)
Alk: 9.9
Calcium: 460
Mag: 1350
PH: 8.2
I recently started dosing Alk and Calc using the Red Sea products. I have tested Alk and Calc every day for about a week now, at the same time in the morning and night, and don't notice any fluctuation.
Here were my thoughts / things I've tried:
1) Increased my water testing
2) Dosing NoPOx to deal with Phosphates and Nitrates. 3ml per day to just slowly bring it down.
3) Increased the amount of GFO in the reactor mixed with Carbon
4) Rented a PAR meter, noticed the lighting was in the 100-300 range throughout the tank, so I raised the lights 2 inches.
5) Messing with Fuge lighting to try and get macro to grow to help manage the phosphate
I'm just at a loss. No idea what's happening or how to stop it. Thanks everyone.
