The best filter for the ocean was coffee filter and gravel  if we used oysters to put in the water it would be hard because oysters are decreasing.

    Very interesting. How would we increase the oyster population? The oysters love to latch on to rocks and other hard surfaces. Can we make something that would help make more comfortable habitats for oysters?
