Hi all,

IG plaster 22.5k gallons
FC 3.0
CC < 0.5
pH 7.2
TA 110
Cal 240
CYA 55

I have been adding baking soda to tweak up TA. Also, I know I need to raise calcium. But finding it has been a nightmare. Suggestions from this forum include Dowflake (road salt?) and something Lowes has in 5 pound bags. Well, here in the Sierra Foothills, we rarely need to salt the roads (global warming ) and the local Lowes have never heard of the stuff. Our smaller building-supply center -- Meeks -- was able to order "Calcium Increaser" by HTH. But it's nine bucks for a four-pound jar!

I really hate to rehash this subject, but I could use some more specifics for what to buy. It's only calcium carbonate, right?

Peace,
Paul
