:rolleyes: POttsy and Cecil I'll trade you my alkalinity for yours.
Man I wish all my clients had that problem. Most ponds in GA have 8-10 ppm. We struggle to get them above 20 for more than 3 years with app. of 4 tons lime/acre.
My guess would be to lessen nutrients. Plants around the pond might help soak up some b/f they go into phyto production. Also probably not the most popular choice but dye might shade out some then help increase vis. also light mist of copper could slowly kill "bloom". Heck what do I know I only have to do these techniques when dealing with an old hog "poop" pond.
