Fishman, My problem is that I cant get my alkalinity up even after adding 20 tons over two years of ag lime. My alk is only 16 I would think this is why I cant get a bloom. My pond is only 2.5 acres cant figure why I cant get the alk up. Thinking about just going with hydrated lime at a rate of 100lbs per acre. What do you think I should do.

Thanks Jake
