Eric, can you get a few pictures with just the whites on? It will be much easier to give you an ID if we can see the algae more clearly.
That said, the sand looks like either diatoms or possibly dinos. By the acan looks like possible bryopsis. Again, we could give a more precise answer with better pics.
