I need some advice on the size of the mini-ponds. I am thinking around 1000 sq feet + or -. They will need pond liners. What is the most economical shape and size? How deep to be able to sustain minnows over the winter with a small diffuser? There will only be a 100 or so brood stock left in for the winter. I think I probably have enough excess capacity (4.5 cfm 35 psi) with my current compressor to handle the future expanded 1/4 to 3/8 pond and some minis?
