Maybe I should clarify something. I have a 1 acre pond that is lined. Approx 16ft deep and around 700ft around. I'd say the average depth is approx 8-9ft due to a steep slope on the inside.
I'm looking for something that is cheap maintenance. Chlorine would be on-going costs which I'm sure would be more expensive than the alum I've been adding every year (700 pounds) plus time it takes to spray it out.
I figure the solar units will be the most expensive part, while the pumps and filters would be somewhat cheap. Once the clay is removed from the water, I would really be more of a UV filter setup.
