pond aerator [RE-wrenches]

Dear Roy and all,

--  "Come on Windy, you can do it!"  -- says Roy.

That's how my customers urged me on in early 80's when they wanted 
solar water pumps ... And look at all the trouble it's gotten me 
into!  :- 0=

OK, joking aside (?), I've rigged air pumps to motors, LCBs, PVs, 
etc, and made bubbles in the sun. For daytime de-icing (opening a 
hole) in stock tanks and ponds, we have been successful, even as high 
as 10,000 feet in the Rockies (a trout pond, the fish survived 
numerous winters like never before). However, I don't know how to 
quantify the result.

When the purpose is oxygenation to effect the biology of the pond, 
it's a more daunting problem. I can't specify a system to meet the 
customer's need when the customer doesn't have a clue how to quantify 
his pond conditions, and I don't have the background to interpret 
environmental data if I have it.

We don't get much call for pond management here locally, so I don't 
have the hands-on or even good observation. We need to hear more 
about YOUR experience, Roy. Tell us more about what works for you and 
what the remaining problems are.
