So my tank has been up for about 2.5-3 years post move at this point and everything was going great. I only had a few SPS over the course of that time but they were doing great until my salinity spiked to 39ppt and they browned out. I slowly brought it back down and settled it back at 35ppt. In that timeframe I lost 2 dart fish unfortunately but was able to remove them within hours of them both dying since my tank is in my office. Nothing else has died in the tank. My BTA split during the time it was at 40ppt as well and that is when I am pretty sure I lost the dart fish.
So its been closed well over a week since correcting the salinity issue, not sure what happened there with my ATO
Everything in my tank at this point is closed up and I cannot figure out why. My parameters are on par:
Salinity: 35ppt
Nitrate: roughly 0
Calcium: 430
Alk: 8.2
Temp: 78-79
Checked for current in the water and from what I can tell there is none.
I have been doing religious water changes every other day sometimes 30% and sometimes the duncans will partially open after that or the nems will move but the rics and toadstools and zoas never open.
I had a 3D printed nem guard on a power head in the tank for about 6 months printed with PLA but was reading that it might breakdown but not hurt the tank. I've also removed that since the incident.
I just cannot put my finger on what may be causing it and much longer this may not end well for all the inhabitants in my tank. The fish have regained their appetite which they didn't seem to have when the tank was at 40ppt. No snail or shrimp deaths that I can see either.
Any ideas? Do nems splitting release toxins? I also have a bag of carbon in my filter sock to hopefully remove anything unwanted in the water.
