Thanks Guys! I used Aqua shade and I kept adding until IT WAS TIDDY BOWL BLUE!BRUCE i JUST SOLD THE WIFE ON THE bg ONLY POND AND i HOPE TO BE DIGGING BY AUG AFTER THE NEW HOUSE IS DONE. She is a good girl as I am building a 24x40 pole barn to put the aerator in so it doesnt get wet.She is into the pond now that it doesnt look like a cess pool.
