A few questions for the board.
In June 2004 we constructed a football shaped 60'x 80' 6'/7'deepest 4' average depth pond. The pond is semi-shaded.
Our goal is to have a pretty place to relax and fish with our 7 year old son.
We had leakage problems that took about 18 months, 2100# of Bennonite and 1000# of Soda Ash to figure out.
In April 2006 we stocked 100 HBBG, 50 CCF, and 30 LMB and 3# of Fatheads with very little visible loss.
In September 2006 we added another 50 CCF and 20 LMB with 2# of Fatheads.
All fish were stocked as fingerlings and we have since added dye for water color..
We have had lots of enjoyment this spring catching mainly the HBBG, a few CCF and LMB.
Very happy with the growth rates so far. We have fed these fish daily (except for Winter).
Questions-
Does this pond require areation? We noticed in August of last year the fish were extremely lethargic during feed times.
If so could someone recommend a system for this size small pond? If required would the Air2Go bubble tube system work? DO NOT want to stir up the bottom because of the bennonite.

Structure-
We tossed in a couple of truck tires last winter.
Any ideas? Not looking to clutter it up but I'm sure they could use something better.

Do y'all reccomend we have the soil sampled?

Thanks in advance to any ideas or recommendations. I would also like to thank the people at Purina for sponsoring the show on RFDTV, very informative.
