Introduce Biological Cleaners to Water Tank

What happens here

The acquired snails (and goldfish, if using) are introduced into the water tank. The creator explicitly states that these organisms effectively clean the water. Previously, the water would have been cloudy and developed slime, but now it is clear due to the actions of the snails. The presence of the snails in the tank actively consumes the algae and other organic matter that contributes to cloudiness and slime.

Goal: Initiate the natural cleaning process within the water tank.
