I put together an "industrial strength" pond bubbler that doesn't use much electricity. It consists of a 3" poly tube with ends and air compressor couplings.
I have a 2 cylinder, 3.5 HP, 20 Gal air compressor. This works SPECTACULAR! The compressor comes on about every 30+ minutes for one minute. Little energy use. The bubbler works spectacularly.
If I could do one thing different the ONLY thing I would do is not drill so many holes. I had WAYYYYyyyy too many holes and had to use electrical tape to plug some up...
Anyway, here it is and it really, really works well... Total investment, if I include the cost of the compressor I *already* owned, is about $350. If you have a good compressor, about $50. However your price will DEFINITELY be different depending on how much air hose and how many fittings you need.
STILL, such a great deal and does a spectacular job!
