My son is 10 years old and has had an aquarium since August. this morning he came downstairs complaining that the water was cloudy again. I discovered the rocks covered in food where he had obviously overfed them. I performed a 25% water change with the vacuum and netted as much of the free floating food as I could. My question is, would it be okay to do another 25% change later this evening to vacuum the gravel again?
