Surprisingly there is not much muck on the bottom as I've been testing it with a pole in the center off the pier. I can only penetrate in inch or two until I hit solid clay. I attribute this to the two membrane diffusers and rotary vane compressor I run from spring to fall. Not bad for a pond that was built in 1994.

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