in the 40g with the firemouth I’m going to remove half of the gravel tonight and replace it with sand so the cichlid can sift for food. The tank has a good amount of plants so the gravel isn’t completely siphoned on a regular basis. Should I siphon the gravel on one half and use a red solo cup to scoop out gravel to try to stop as much debris from floating around. What’s the best way to do this
