Get a test kit!! Pool store testing of CYA is massively unreliable; some stores are fine; some are totally random. We constantly recommend the K-2006 (see page in my sig) and I can't recall any negative feedback (except, "this is kinda complicated", but there's no way round that one.) However, if Walmart's in your area have them the HTH 6-way drops kit is ALSO made by Taylor and is a great place to start. It DOES include the CYA test.
