Dinoflagellates ... is there an end to this nightmare

[clintyiu]

Been there. It was a horrible messy end to my skimmerless SPS experience. The corals were doing great until I vacuumed the substrate with a closed loop micron filter and the dinoflags... started. You can actually see particles of it multiplying within seconds!

Use carbon, phosphate remover, clean out your skimmer but don't change the water and filter out some of the lighting. It will dissappear.
