There is an interesting thread in another forum where people are throwing all types of stuff at different types of dinos-from metro to household bleach.

Two members on that thread have what look to be Amphidinium populations on the sandbed. Their fix..vacumm the bed, reduce lighting to 4-6 hours, bottle of dr tim's, introduce pods and plankton. Repeat every few days as long as there are visible populations on the sand.

This seems like a pretty non-invasive way to do things. Going to try this when the goods arrive prior to using meds or caustic solutions.
