esshup (and others),
Is there any type of emergent shallow water plants that can be used to take up P during the growing season, and then cut back in the fall with the plant material removed from the pond basin so that the nutrients are NOT recycled into a hypereutrophic pond?
(I was just thinking that if you lowered the pond in the fall to remove the tilapia, you could also cut some plants at the same time.)
Chemistry, plus tilapia, plus plants might be an effective three-pronged approach to get up to "drinking" water level?
