Pottsy,

I know the feeling. I'm always tinkering with the ponds myself. I debating whether to spend the money and treat the turbid pond with some Aluminum sulfate. Clarity with a seechi dish is only 13 1/2 inches. Don't believe I would need a buffer as the alkalinity is so high. I'm concerned that sight feeders may have trouble feeding.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
