Dinoflagellates ... is there an end to this nightmare

[Bob I]

I think the stuff has a bad rep, plus it's expensive. But if it would work, you'll be glad for it afterwards I think.

Just a thought, if all else is failing.

It has a bad rap only among those who are unaware of its fine qualities. It has a good reputation among some very experienced reefers. One of the moderators on Aquariacentral has said some very good things about it. It is well worth giving it a shot. My opinion of course.
