I couldn't understand why the big brown icky presumably cyano break-out.
After siphoning it up a dozen times, I went on a search, dismantled
where I had last seen the elusive blue linckia, and found its puny
smelly remains. Serious mess. I've changed the water, dropped in one
measley Maracyn tablet, which I'm assured won't do any significant harm
is such small doses, and I'm repeatedly emptying the skimmer which
really goes into major foam production after even such a small dose of
Maracyn. Is there anything I should or could be doing? Very ugly stuff.

When you say you put in one measley tablet, do you mean that was not the
correct dose? (Can't get this stuff here so don't know the dose rates
and you didn't say the size of your tank)

If that is the case why put it in at all as it won't do the job you are
expecting? All you are doing is breeding resistant bugs!! Please don't
do that, pretty please even.
