LED world domination!
PART ONE
I'm going to attempt to recount my, uh, battle, with dinoflagellates, which I assume to be Ostreopsis sp. due to significant death of my vast cleanup crew (hundreds upon hundreds of various snails) and all herbivorous fish (save for Siganus doliatus, which are immune to the toxins).
I first noticed these slimy, snotty strings growing in various places in my tank sometime around mid-February of last year.
The only event preceding it was the removal of my broken-in and very well-functioning waterfall algae scrubber for a protein skimmer after reading a lot of data back and forth on phosphate and how it can be removed, etc etc. I honestly think that was the breaking point at which my tank took a sharp turn for the worst.
After not knowing what it was, I started spot treating with peroxide daily, which worked, although the slime would come back within a few hours. Shortly after I figured out I was dealing dinos. For the next year or so, I watched nearly all of my cleanup crew die off, lost every tang I would put into the tank (even after rigorous quarantine procedures, which I eventually gave up on), and SPS corals would get the dinoflagellate mucous on them and would die back wherever it touched, leaving them with patches of flesh that would then shortly thereafter die.
Sometime in March I began dosing peroxide, and I mean extreme dosing. I skipped that piddly '1mL per 10 gallons for a dinos cure' **** that you see regurgitated online and straight to dosing 100mL twice a day with my sump turned off, leaving ~60-65g water in my tank. I spot treated as much as I could, and let it simmer for an hour or so. I did this for a few days, and it seemed to really hit them hard, and for a while it seemed like I was dino free - but, as dinos are wont to do, they returned with a vengeance.
I fought them off and on, proactively and passively, until late December. The sort list of 'treatments' is as follows:
Fast forward to December 31st. I'm moving the tank to a different room, and figure that while I'm doing that, I'm gonna see if there is anything I can do about these damn dinos, so I took out the nicest rocks I have (some fresh uncured live rock from KPA) and any rocks that had corals encrusted, and then pulled the other corals out and onto frag plugs, and placed them into a Biocube that had been cleaned out with vinegar, and performed a seven day blackout, in combination with running a new 9w UV sterilizer and dosing ~30mL of peroxide daily.
(light was on there so I could make sure not to squish things)
During day two inspection:
After the lights-out period, I didn't see anything for several weeks. I started feeding the corals again after the initial seven days and they began to recover without any losses. I stopped peroxide dosing somewhere around day 12 or so. All was well, or so it seemed.
By February 15th, dinos had reared their ugly heads again.
It was around this time that I had gotten in contact with user 'Pants' about them. I was to send a sample to him once it stopped being so damn snowy everywhere, but that lasted for far longer than was expected. It was during that waiting time that I learned about dinocysts, aka part of their life cycle where they 'hole up' and form a cyst and can wait years and years and years before bursting to see if conditions are favorable. Disheartened but determined I continue to try and treat, as I know that there has to be some way - but if I don't find any, then I am ok with throwing out all of the coral and acid-washing the rock and starting over.
Pants tells me that one thing that absolutely murder-fies dinoflagellates is a rapid salinity change of 10ppt or more. So I begin prep for doing a freshwater dip. I was not sure how it would affect the maxi mini anemones, sponges, and feather dusters that I have in the tank that I really do not want to lose, so Pants said I could do a half-seawater half-freshwater dip and it will have the same effect, as long as the salinity change is rapid it will do the deed.
Now I'm armed with a DSLR.
This is all that remains of the gorgonian in picture number two above.

I fought them off and on, proactively and passively, until late December. The sort list of 'treatments' is as follows:
- Large doses of peroxide (up to 300mL twice to three times daily in the 60-65g volume)
- Large doses of Dr. Tim's Eco-Balance (which got expensive very quickly)
- Wet skimming
- Very wet skimming
- No skimming
- No feeding for weeks at a time (which killed a few of my already stressed fish)
- Raising pH using saturated kalkwasser
- Raising pH more using sodalime CO2 absorbent media on the skimmer air intake
- Combinations of all of the above.
