So I'm building a small pond in my back yard. Like a couple hundred gallons. The thing is I'm trying to do it as cheaply as I can. So I decided to build my own waterfall box. I decided on an upflow design but was wondering if it would be helpful if I were to put an aurstone in the bottom so the bacteria have some extra o2. What does everybody think? I'll have a prefilter for mechanical and use lava rock for bio. Any input is apreciated. I'll post pics later.
