Pond Water Aeration and Circulation
In order to maintain a healthy pond, it is essential
to provide a system in which the water is continuously aerated to
provide oxygen for the fish and plant life. Without aeration, your
pond will risk becoming anaerobic, allowing stagnation and anaerobic
bacteria to flourish. Not only will this kill the plant and animal
life, it will also become quite smelly. The electricity used and
pumping time will vary depending on the size of your pond. There
are 7.5 gallons in one cubic foot of water, therefore
7.5 x length x depth
x width = pond volume in gallons
A 12 volt bilge pump will
circulate 500 gallons per hour at zero head (how high the water
is lifted) and 360 gph at 3.35 ft of head. If you aerate your pond
4-5 hours a day, every 2-3 hours, you will be able to maintain a
healthy ecosystem. In NYC, there are about 4.6 hours of full sunlight
per day. Combined with 1 Unisolar 64 watt solar
electric module, you will have enough energy to power your pump,
and about 52 watts left for other uses including excess energy storage
in a battery.
