I first posted about this topic a year ago: http://forums.pondboss.com/ubbthreads.php?ubb=showflat&Number=486287
Bill provided some helpful thoughts, and since then I have been continuing to read and research as much as I can, with many books and back issues from pond boss.
One of my challenges is that I haven’t yet been able to find much information on using air lift pumps to aerate and circulate and excavated pond. To me they make a lot of sense - I can get water flowing while discretely adding oxygen to the water, all with less energy and less maintenance than a traditional pump - but I haven’t been able to find much info on others using airlift.
I’m wondering if anyone has any good links to information on this, or if there are any “gotchas” that I might be missing. Any thoughts are appreciated
