Ny, I would buy an adapter fitting, 1/8 male to 1/2 or 3/4 female. The reason I suggested 3/4 poly line was to match your higher CFM compressor and to reduce air flow loss over long distances. If it is a short run to the pond from the comp. location, then 1/2" should be fine. Also purchase barb fittings (king nipples) that have 1/2" male pipe x 1/2" barb to fit into poly line and use a hose clamp. You will need a garden hose adapter at the soaker end to screw it on. I used a 16 foot soaker hose and suspended it off bottom with rope and javex bottles. Coiling it in a bucket may work well also, providing the hose does not kink and cut off air supply. You should look at putting an adjustable relief valve at the compressor end in case of blockage somewhere. This will require a few more fittings to adapt it. Hardware store should be able to supply everything for this job, or Revy if you have one there.
