Algae Indentification and Help Please

[monocus]

i agree with the dinoflagellates .according to algae: a problem solving guide,let it run it's course-discontinue water changes-boost alkalinaty with buffers or calcium reactor.use kaulwasser for top off water.use activated carbon.it sounds like you have new tank syndrome -in other words your tank hasn't been running for a few months.do not let snails eat this as it will probably kill them .and my advice to you is stop using h2ocean-i had serious breakouts of cyano in my reactors where i shouldn't have any at all
