I thought I found a source for Ag Lime. My local feed store said they carried it, but upon further questioning, it turned out to be hydrated lime. So I kept searching. Turns out Tractor Supply carries 50# sacks of Calcium Magnesium Carbonate for $2.99 a bag. In the Q&A section, they stated this was NOT HYDRATED LIME and can be used to balance PH in a pond. I guess someone was looking out for my little finned buddies. Found the right stuff for an even cheaper price. I'll be working near that store tomorrow, so I'm hoping they have 10 sacks.
