The topic of liming is of paticular interest to me because I have added over 30 tons to my 2.5a pond over 4 years with no results. By this I mean I cant get my alkalinity above 15ppm. I have limited flow thru but cant get it above 15. I apply the old fashion way with a sheet of plywood on my johnboat shovel on shovel off, man alot of work for no benifit. I have started using hydrated lime 50lbs per acre and for the first time am able to get my alk up near 30 and get a good bloom. I think the limiting factor in my pond is nitrogen because I added extra nitrogen this year along with the hydrated lime and established a good bloom. I reapply the lime every 6 weeks as it drops near 20.
