      Not really. You probably should avoid putting heavily polluted water through them though. They are the oceans waste buckets for poo water.

      Oysters actually need clean/unpolluted water. What they eat and clean is sediment, phytonutrients, and phytoplankton. Well at least that’s what I was tood by an oyster farmer. They clear the water which is good for the grass, and the small fish, which is good for the big fish and so on.
