I would run from the pump and manifold two black polyethylene irrigaton hoses 5/8"ID (sold as 1/2"). They sell it in 400ft rolls around $50 each. This allows convenient control of air flow at the pump. One 3/4" ID airline from the pump to the valve box at the pond will also work but you will need a valve junction box buried near the pond edge.
