Evan,
You may be one of the few people I know who actually finds the acid and base demand tests useful. But then, as a person who saw LOTS of pools with lots of problems, you might have needed that. But I've never, ever had a need with my two pools. And most people don't. Ben's kits, when he was putting them together, didn't have an acid or base demand test. I STILL use my old PS-233 as my main kit, constantly replacing reagents.
