Aquarium Advice Apprentice
I am in the middle of a build and saw someone had posted on youtube a return that went under the gravel. Does anyone know anything about this, pros/cons??? I have never heard of this, but am willing to try anything new with data to support it being beneficial.
so does anyone know of a return being run back into the aquarium under the gravel?
