What about this one from in the swim-
http://intheswim.com/Pool-Chemicals/...quid-Solution/
It says it tests for "free" chlorine, total chlorine, ph and alk. No idea why the quotation marks, but that should probably concern me...
This would only leave me without a test for CYA, but that is something I just need to test once or so and perhaps can get it done at a pool store fairly accurately, right?
