Beneficial Bacteria

My bio filter and all lines are drained. My Savio runs and circulates through the waterfall all winters. This way nothing is stagnated during the winter plus I have movement and zero ice.

My main feed is a three inch line that runs 8 feet below water level due to the topo and is buried 4 feet below grade blowing that line is no easy task but the pump makes short work of it . I just have to flush the line first
