Okay. Been slamming for two days now, pool has shown visible improvement, and now I find that I've used up all my R-0871 in my K-2006 kit!!! I ordered more from tfttestkit.net, but what do I do until I can test? Should I just blindly add 3 or 4 gallons a day to keep it high until I can test it again??? Has this ever happened to anybody else? USPS from North Carolina to Tucson is a looooong time. Suggestions?
