So I have a few patches on the sand bed (not on the rocks/coral) and I thought at first that it were diatoms but I bought a microscope and checked it out and I dare say that it's dinoflagellates I'm thinking Amphidinium or Prorocentrum? What do you guys think? I also put a small climb of sand under the microscope and they are full of these little buggers. See last photo...
