TF-100 Test kit...
CA stayed stable around 275 for most of the summer...its drifted down to 250 for the last month.
TA has dropped to around 65 (only a slight color change with the 7th drop of test reagent)
So I'm at the very bottom of the CH recommended level, and a little under TA.
TA is easy to pick up a small amount of baking soda, the calcium chloride...I've only seen larger quantities than I necessarily need of it (maybe 100oz).
Where do I REALLY want these numbers, and how often should I adjust them?
