What part of VA are you in?
I have the same water issues it sounds like as you in central VA. I barely register any alkalinity. My water started out blue green when the pond first filled last year. This year it turned brown green but good visibility. Do you have flow into your pond and if so, will adding the lime raise the alkalinity and keep it up for a while? I'd like to add lime to my pond but and wondering if the 10-20 GPM inflow will just flush it out.
