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.
I would've expected their to be a lot more muck on the bottom than that. At a friends pond the muck has been building up for 50 years. The pond used to be 14 feet deep but now it's only 5-6 due to the muck.
I'll bet he didn't use diffusers to mix the water column keeping the bottom aerobic, which allows aerobic bacteria to consume waste more efficiently than anaerobic bacteria.
If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
