Approaching total coral wipe-out

[asylumdown]

Actually yes. I have my own theories about cyanobacteria but my experience with it is that once it's given the opportunity to proliferate it's very tenacious. It took advantage of an opportunity and became a threat in its own right, even though I seem to have corrected whatever it was that started this in the first place (I think it was biopellets, but who's to say really)

I left the chemi-clean in the water a day longer than recommended before doing the water change and I'm letting my skimmer do what is essentially another slow motion water change right now, but even in just three days of the the 'drugs' working their magic, corals that were continuing to decline under advancing sheets of cyano seem to be forming hard lines in the spots where the tissue had been dying. That's generally the precursor to new growth plates IME, so I'm optimistic.

Whether this will have long term effects on stability in other areas I can't say, but as a short term solution it seems to have helped
