Thought I'd post a couple or three of my low-energy scapes. Excuse the less than perfect images, these tanks were up and running, and torn down well over a decade ago. They all started life pretty much as Walstad scapes but ended up with regular water changes, fertz dosing, and decent filtration. But remained without CO2 injection throughout their lifespan.
