Trying to see light at the end of the tunnel

My reef definitely got cooked by overdosing bacteria in recent months, and it took me a while to figure out what was wrong (as you know if you read my blogs). I'm doing a soft reset rather than a hard reboot now. I'm not going to dose any additives for the next six weeks. I pulled the biopellets offline to stop any additional bacteria introductions, and I'm doing some big water changes to hopefully help the corals turn around.
I feel like anything I do will spook them, and I don't want to push them past the tipping point, as they are already leaning pretty hard the wrong way. Colors are off, some polyps are gone, and declining issues continue. UGH. Oh well, I'll keep at it and see what I can do to move things in the right direction again.
If you are new to my writings, let me explain my thought process: I used to have a very high nitrate problem in my 280g because I was misreading my Salifert kit for YEARS. Thought it was 7 ppm, when it was actually 80 ppm. So I did what I could to bring it down with water changes, and turned to vodka dosing. It took seven months of daily dosing, but eventually it hit the right threshold and brought them down. [ link ]
When I set up the 400g in 2011, I decided to use biopellets and Prodibio from the first drop of tank water, and get away from vodka dosing. The biopellets and Prodibio worked great for 3.5 years. The Phosphate and Nitrate levels stayed low, I could feed more, and my corals were happy and colorful.
It was only a few months go when I started overdosing the Prodibio vials (they are bigger and had a different rating that I didn't grasp [ link ] ), and things started going south. I hadn't had any problems and wasn't trying to run a ULNS system - just a clean one that let me feed my fishy friends frequently.
But something was amiss, which I've been blogging about on ReefAddicts over the past few months. It wasn't until the night before MACNA when I finally figured out what I'd done, and then went to talk with the guys at the Prodibio booth. After discussion and serious thought, we agreed that my dosing coupled with the biopellets was definitely the likely culprit. [ link ]
Knowing this information, I figured I'll just taper down with my dosings but I think the domino effect was already in sequence. It has become apparent I had to do more. That's why I pulled the biopellets entirely to stop any additional bacteria production, although the reactor only had a couple of inches of media (maybe 2 cups worth) in a 450g liquid volume system. Once I did that, the skimmate finally returned to the normal look I'd seen for so many years. But the corals are still declining.
So I'm going to focus on some big water changes, even if it does end up splitting all my anemones in the 60g. I'm hoping a reset will enable to the DNA I still have in the system will turn around and enrich itself and get things heading in the right direction once more.
I've never had a full tank crash in all the years I've been in the hobby. I've had my share of tank leaks, which totally suck and just screw up forward momentum with temporary setups and waiting for replacement tanks, but this one was definitely a stealth-mode attack. Since I've employed this method of dosing for years, it was a little surprising that it was the cause.
Now I just have to pick up the proverbial pieces and work with what remains. Not much to celebrate on the 10 month anniversary of the 400g 2.0.
