I want to change substrate but where do you get rid of 100 lbs of old gravel from a 100 gallon tank Advice?
Save the gravel in an empty plastic garbage container........I leave my tanks bare, without any gravel, cleaner this way..................You never know when you will want that Midas Devil, and then there is no gravel for him to push around..........100 pounds of gravel will fill a 75g perfectly for tankbuster like a red devil/Midas to push around...........
