Dumping Water

The caretakers dump water in the tank every day. Why? First, they suck out their food and poop that are on the floor of the tank. They siphon the dirty water into a bucket and then dump it into a sink. Next, they take a big jug filled with water that has been sitting out overnight. They dump that water it into the tank. It takes about two jugs to fill it back up. Now the water level is back where it was when they started! They refill the jugs back up and set them on the counter so they can be ready for the next day. This is so the chemicals in the water evaporate, which makes it safer for the fish!
