: The Pond-Vent ice preventer
900 includes a
1/2" cascade nozzle so that it can be used as a
fountain pump during the warmer seasons of the year.
Every winter, the same problem occurs: The pond freezes
up completely, and toxic gases build up at the bottom
of the pond and cannot escape. Toxic gases create a
lack of oxygen in the water and cause the poisoning
of living organisms. Due to this lack of oxygen, fish
and microorganisms have practically no chance of survival.
The OASE Pond-Vent Ice Preventer 900 is the solution
to this problem.
How does it work?
The Pond-Vent pump pulls the lower layer of water
(which has been warmed up to around 39°F by the
higher temperature of the earth) from the bottom of
the pond. The water is then pumped through the hose,
using extremely little energy, and is let out at the
surface directly below the floating bowl. 220 gallons
per hour are being delivered by the Pond-Vent without
breaking up the water layers. The warmth of the water
is sufficient to keep a hole with a radius of 11-11.5"
ice free. This allows toxic gases caused by decomposition
processes (fish excrement, leaves, etc.) to evaporate.
This aeration process helps ensure the survival of
fish and other microorganisms. In order to operate
the Pond-Vent Ice Preventer properly, the pump, which
hangs on the floating bowl, should be 8" above
the bottom of the pond. The depth of the pond should
be 24-32". The enclosed hose, which connects
to the floating bowl, is 32" long and can be
shortened if necessary. This product has been thoroughly
tested and functions in temperatures as low as -4°
