I said in a previous post I lived in Canton, Michigan. Near Livonia, Westland, Plymouth, 25min from Ann Arbor. That vacinity if you didn't know where Canton is.
Sorry, did not catch the town post. Power heads just push water around. Alot of critters in the tank eat from the water column (what floats by) and the circulation adds oxygen to the water. Airstones and bubblers are not recommended for sw.
