Thanks Brad, I'm not too clear on this diatom filter thingy but I pretty much figured that the filter may keep any dinos out of the water column but certainly not clean your tank of them.
The only thing I have had luck with so far has been the complete covering of my tank with blankets and lights out for at least 2-3 days. I did this the first time I had dinoflagellates (2002) and it seemed to fix the problem. However at this time I did not have SPS corals and wasn't concerned about losing any corals (softies rebound from lack of light better than SPS it seems). Then in the fall of 2003 I had a brief bout with dinos and still haven't figured out what I did for that. This batch of dinos just wasn't interested in going away at all. I did lights out for 4 days at first, then tried just actinics for a few days, tried boosting alk, increasing skimming (mainly just adjusting knobs randomly
).
Oh and of course I'm not discounting the fact that by the time I get home today the dinos may have started up again. I really wouldn't be surprised at all. They're persistent little buggers thats for sure.
