Theo,
Can I just put the compressor in barn and run say a 1 inch PVC line 350ft to the waters edge and then split it off at a manifold to 2 or 3 diffuser set ups on 1/2 or 5/8 weighted airline. probably cost less than running 230v and buying a cabinet for compressor etc. Also how loud is a 1/2hp rocking piston compressor compared to say a lg garage air compressor?
