The front panel is two sheet of glass. One is sliightly taller than the
other.
The heart of the ventilation system / front pane defogger, is a linear
piston air pump, which provides the forced air. For internal ventilation,
this air is pumped into a 5G bucket, which contains RO water and the
ultrasonic fogger (on a timer). An outlet in the bucket lid has a hose
barb, with a 1" flex hose into a bulkhead in the floor of the tank.
I can control the airflow via a ball valve - add more / less air. I can
also force the air THROUGH the RO water, allowing it to gain some
humidity. The ultrasonic fogger will kick in from time to time, allowing
the fog to be pumped into the viv. The fogger itself is suspended from
a stryofoam 'boat' to keep it at the optimum level below the
waters surface for maximum fog production.
I'll explain the hot air defogger tomorrow.
