Ag lime.
If you can get a spreader truck to it I would have them back up or drive around it with the truck. THe truck will throw it either in a 180 degrees or 90 degrees with plate installed. It throws it 60-90 feet in an arch pattern.
There will be a minimum amount around 5-6 tons at about $40/ton. I had them back up to pond in about 5 different spots, then drive around the dam and up the watershed. Guessing I put 3 tons in pond, and 3 on ground. I wish now I would have had them put more in the shallow spawning areas and made it have a little more gravel type bottom. Next time that is what I will do.
It raised my Ph from 7 to 8.5 and alk from 60(I think) to 120.. I think you will benefit from the increaced Ph and alkalinity, plus it will help clear it up. If it doesn't clear it as much as you like, you still have the Alum and gypsum option.
