The Main Hydrochamber is a room found at the bottom of sea level in Torvus Bog.
Samus first walks through this room to obtain the Gravity Boost in the next room, the Hydrochamber Storage. She encounters the Alpha Blogg when she walks through here again, and the creature destroys the tower in the middle. After she defeats it, she reaches the Hydrodynamo Shaft by using her newly-obtained Gravity Boost to move from ledge to ledge. A Portal to Dark Aether can be reached via Spider Ball Tracks.
