Okay, it's been three months. Time for an update.
It all went to ****, basically. A combination of neglect, equipment failure and adding too many fish added up to a minor crash, severe cyano outbreak, massive increase in nutrient levels, and the loss of perhaps 50% of my corals, and maybe up to 75%. We'll see how it ends up.
The longer version is:
I lost my job two weeks after my last post because the LFS for which I worked closed, and while I immediately found a new job with a local aquatics wholesaler, the new schedule threw me for a loop. This meant that when I got home after working a 5am to 2pm shift, I wasn't really up for doing maintenance. Because I wasn't doing maintenance, I wasn't checking things I normally look at daily/weekly. This led to my alkalinity bottoming out, due to my alk solution running dry in my doser. This also led to my 3L Seachem Matrix reactor having a pump failure. At around the same time as those two things, I added a number of new fish. Not an overpopulation by my reckoning, but I increased the feeding to try to reduce stress. So alk goes down, corals stop growing and consuming nutrients, Matrix stops working and consuming nutrients, fish level and feedings go up, increasing nutrients to over 100ppm NO3 and 0.5ppm PO4.
I got a cyano outbreak, but I didn't want to deal with it, and kept putting it off and putting it off, which made it worse and worse. At one point it covered 3/4 of the tank, including all three visible windows on my tank. My skimmer also failed during this time, and rather than fix it, I just unplugged it and continued ignoring the tank, as I couldn't muster up the effort to care about it.
Anyway, all that to say, I made some booboos. To rectify it, I did a 50% waterchange to remove as much cyano as possible, then began a 4 day blackout, while doing two full doses of Ultralife RSR, 48 hours apart. I have done another 35% waterchange today, and plan to do another one on both Saturday and Sunday. Next Wednesday, I will do one last RSR treatment (with no blackout) to hopefully ensure I kick the cyano for good. Meanwhile, I will continue 35% water changes 3 times weekly for the next two weeks. At that point, I will test my water and see the difference my work has made. Hopefully it is significant. If it's to my satisfaction, I will start carbon dosing with vinegar, and continue doing 35% water changes weekly for the next two months. If things seem to be on track, I will reduce water changes to 10% weekly thereafter.
I took some pictures, but I'm only going to post the FTS. Please compare with the last FTS I took.

Total losses include:
Hot pink stylo
Green stylo
Purple stylo (my favourite)
Red millipora
Two fiji mini colonies
One fiji frag
I will probably lose another fiji frag, one of my tricolour acros, my hawkins echinata, and possibly my green slimer (yeah, it was that bad).
We will see. I'll try to keep this more current.
