If you don't have electric at the pond that's no big deal, the compressor can be where the electric is and black poly tubing can be trenched to the pond, attach to a remote manifold box and then distributed in the pond from there using the weighted tubing.
I plumbed the "manifold box" at my second pond with galvanized pipe and brass ball valves. After 16-17 years, corrosion from the dissimilar metals has it leaking and I have to replace it (have been thinking of all brass but might go all plastic - although in Ohio I worry about condensation in the latter freezing and breaking it - that probably wouldn't be as likely in GA). Consider this problem and avoid it.
