Hey everyone I have a 16 gal Nuvo that has been running for about 2 years now. The tank has been extremely healthy, and I have been keeping SPS mostly with some LPS. It has been a thrill to finally have a nano SPS tank that thrives. I recently went on vacation and for about the last month the tank has going downhill. I had someone sit the tank and they dosed / fed the fish. About a week after I got I read something on my Hydra LEDs on how to give the tank more of a 20K look, the settings were a little off my normal settings so I set an acclimation of 20% reduction over 3 months. Everything was fine and then one of my frags started to RTN. Thinking it was maybe that there was overfeeding or something I did a 3 gallon water change. Then in the next few days another SPS started RTN'ing and then another. My immediate thought was AEFW. The first frag that RTN'd was the newest and was about 3 weeks in the tank before it started. I did dip the coral in CoralRX before it went in, but knowing that something may have made it into the tank I did not want to rule it out. I read that if you do a Bayers Treatment on the corals the AEFW will come off the coral and you will see that you have them. When the 2nd SPS started RTN'ing I immediately removed it, including the base and put it in a 15 min bath of Bayers. Since the coral was mostly dead at this point I was taking chances and wanted to see. After the 15 minutes I rinsed the coral in another bath of tank water in a separate bowl. To my surprise there were no AEFW in either bath. To further solidify that it was not AEFW I noticed that 2 of Montis started RTN'ing as well in the next few days. As I currently sit most of my SPS has browned out or RTN'd. My LPS (Blastos) that I have had for 2 years will not open fully anymore either, this happened in the last week or so.
Parameters
Nirtate - 0
Nitrite - 0
Ammonia - .25
PH - 8.2
Phosphate - 0 (what the test stated)
Cal - 420
Mag - 1350
ALK - 10.6 (This was the only thing that spike as I normally kept this at 9.3, since the test I have reduced the dosing to bring it down)
SPG - 1.025
The only thing that I changed was I started dosing Brightwells Reef BioFuel. I was dosing it for about 2 months prior to these issues taking place, but I have read that carbon dosing can lead to SPS RTN. Alk is the only thing that changed and it may have been overdosed when I was on vacation but I have not read it leading to RNT. I think the browning and the corals not opening as from stress but that is my guess. So far I have maintained my normal 2 part dosing and mg to keep stable levels and I quit dosing the BioFuel. I have been doing weekly 2.5 - 3 gal water changes but have not seen any improvements. Any thoughts would be great appreciated.
