I use a small gast compressor about 1/8 hp feeding 30 ft of black garden soaker hose that I cut and put a fitting on it to attach to the 1/2 inch line that I use between it and the air pump. Used 8 ounce fishing sinkers that I poured and put one every 2 ft or so on the hose and line and drug it into the pond from the far side with some line. Works very well for me with my 1/3 acre pond and keeps my cats fat and happy. I normally run it 24/7 from May until October.
