Sorry, what's GFO?

Along with Phosphates, GFO also removes Silicates, so I would change it weekly for a month and see what happens. Have you checked your source water for Silicates?

The silicates test was negative. I have live rock and live sand (aragonite, caribsea) in there. What would other sources be? I use RO/DI water.

BTW Dinoflagellates will have a whip tail under the microscope.

Thank-you! I'll get drew to bring me a sample today and I will try to post pictures from under the scope.
