I would recommend surface aeration but what type would need to come from someone else. My recommendation is entirely based on research - lots of internet study, you tube videos and talks with folks who were not equipment vendors. I sometimes comment on this forum to pass on what I have learned and save someone the hours and hours of research I put in. Sometimes I comment and have real personal experience and knowledge. This topic combines a bit of both but I haven't personally owned a surface aeration system.

Best of luck and let us know how it goes.
