This oil-less compressor works well for continuous pond aeration. Its higher pressure allows for aeration in ponds up to 35' deep. Also because of higher pressure, this air compressor can be located up to 2000' from the pond and still effectively operate, making it a good choice for ponds needing aeration but not having electricity nearby. Each compressor comes with a 6' power cord and inlet air filter. One year warranty.
You should stop feeding your aquatic plants about a month before the first frost in your area. Even in areas that don't normally have frost, plant growth slows in the shorter, cooler days of the fall and winter months.
