The water in both tanks is from the same time and place. The tank on the right has oysters. An adult oyster can filter and clean up to 50 gallons of water per day.

Everyone…I would like to put oysters everywhere.

oysters are a very good indicator of healthy water! In part bc they help keep it clean–

They’re also delicious. I see no downside.
