aint that bill cody something?....great posts...great thread...
just my little thought for you derek.....perhaps aeration would help yer quest? sorry if i missed that you are already aerating.
my pond was ultra clear w/ alot of weeds until i started aerating (regularly) w/ bottom diffuser. i dont go 24/7, just through the night and until the sun hits the water in the morning. it has kept the pond turbid (w/ phyto bloom...not suspended particles) which has reduced the sunlight penetration and the excessive weed problems. it has also brought oxygen around and into the entire water column so fish are at all levels.
