I'm enjoying the banter. Don't stop on my account.

Seachem Reef Status Carbonate test shows that total alkalinity is 3.2 meq/L (9 dKh).

This test confuses me. I assume that total alkalinity is what the API test tests for. But, there is a second part to this Seachem test: which tests for borate alkalinity. Subtract the borate alkalinity from the total alkalinity to get the carbonate alkalinity.

But, since the API test is so simple a trained monkey could do it, I assume it is total Alk.
