What does everyone think is the best solar aeration option out there? it can be a direct drive (works only when the sun is out) or a complete kit you've used that works well.

Talking about the direct-drive systems, does it matter when you aerate your pond? Like what time of day/night? Is it better to get something that moves a lot of water in the day, than something that moves a smaller amount throughout the day and night? Like a 5 cfm solar setup that works for 8 hours a day vs a windmill that might average out to 2 cfm over the course of a day.

Thanks!
