LB and ML, both your ponds sound just right depth and area for the small system. TKhe thing that concerned my about the Malibu system, is that no battery is mentioned. At a 64 watt panel, that tells me that is is an extremely small compressor and will only run during the day. LB, with you just now stocking, and winter coming on, new pond, yu won't need anything until spring, but will have info by Thanksgiving.
ML, when will yur pond be ready. If you have a pond similar depth, you can do testing on it. What is the compressor you are using on your smallest pond.
