I've put ~125 ton of crushed limestone in the pond since I cleaned it out. It also gets the runoff from ~500ft
of the lane to my house. Most years it takes ~50 ton of inch-base crushed limestone added to that section
to keep it in good shape. Every time it rains hard enough to run off the pond gets a dose of ag lime.

Wow, Augie! Even with liming, my total alkalinity & hardness are in mid 40s.
