Pond built in july. About 1/4 acre. It will get to about third full and then drop to a quarter full pretty fast.Within a week.Hoping DB-110 may be the answer..Saw your posts on the trash pump setup and thought maybe we could work together and solve my problem, and saw were you wanted to add more to your pond. I would just like to have your previous experience as I want to have as much success as possible.
