Today we prepared the gravel for our shrimp tank. We first got the tank and filled up the tank with gravel only a little bit. Then, we got all of the gravel tanks and filled the carton. Third, we filled the carton only about one fifth the way with water. After that was done, we had to mix it around using our hands and it was fun. Fifth, we had to carefully emptied the carton that had the mixed water and we had to do that process three more times! Lastly when all of that was done, we had to even out the gravel into our three tanks. It was really fun and cool how we prepared the gravel for our shrimp tank!
