Hello all,
My pond is about 1.25 acres, average depth 5-6 feet, trees surround it, it is not spring fed. Water is very stagnant, lots of leaves and debris collect in it, heavy layer of muck on the bottom.

I dug furniture and garbage out of it when we moved in, cleaned the shoreline, treated the water, etc and it looks so much better, but there is an oily film on the surface that won't go away. Fish activity is very low. No real vegetation growth in the water... a few cattails and such, but overall I've got it well cleared. I don't believe there is enough oxygen to sustain the fish much longer.

So my question... would a powerful water pump fountain produce enough oxygen to help, or should I go with the "bubbler" aerator system. And with either, I'd appreciate recommendations on what and how. Money is in short supply and I will be doing it myself. I've got about $600 or so to work with.

Thanks all for sharing your perspective.
