My reef is nearly 13 months at this point and is finally getting some real stability over the past 2 months. While the corals all look pretty now, it wasn't the case 6 months ago.
I'm about to show just how ugly this tank got last summer. All was well until the end of April when I noticed the tank going downhill. Corals weren't doing well, but I couldn't figure it out. The nitrate test kit was suspect, but I kept using it until I finally realized it was off and I really did have 0 nitrate. This went for 6 weeks. By the time I figured it out, it took a major toll on the tank. Lots of zoa's were melting and some of the lps were bleaching.
I began dosing Brightwell NeoNitro which brought nitrate up, but the tank continued to decline.
Then the dinos came...
They took hold and wreaked havoc.
Hydroids spread throughout as a double dinger and then I somehow got bryopsis.
The tank was a wreck.
I was getting mixed opinions on everything and finally sent in an ICP test. Interestingly enough, my calibration fluid was off and my water was actually at 28ppt, not 35. I have no idea if it had always been like this. I now calibrate with rodi since I know that is 0 ppt. It's better to use this than chance faulty fluids. So far so good.
A few of the corals seemed to not only do ok, but still grew, however, I lost 3 hammers and 15 zoas to this. There are a few other lps that have since recovered or are thinking of recovering. The toadstool remains as a very slow recoverer and the goni may or may not ever come back. It's still alive, but has been fully retracted for at least 6 months.
UV didn't work, a blackout worked for a week and then the dinos came back. My McCoskers wrasse ended up dieing about a day after the blackout which added to the misery. I have a couple theory's for this.
I took the rocks out and scrubbed them down which helped. The final thing was scrubbing all rocks a second time as best as I could outside of the tank followed by dumping in a bottle of pods. All of my pods had died before so this replenished them. Things finally started turning around in early November and so far so good.
The only real benefit to this whole ordeal was the over 2 dozen apstasia melted down to 1 single one. I still have it currently since it is attached deep within a crack. One day...
It's late and it's possible something was forgotten, but here are some photos.
Look at all of the trapped air bubbles.
Got bryopsis? It adds that warm, cozy feel to the tank.
