I just went through this same thing w/ HTH. The gal I got on the line had no clue about the kit. All she could tell me was my stuff isn't working right - DUH, that's why I called??! Hardness went from yellow to pale yellow - not blue to red. Alkalinity went from Green to yellow not Green to red. All she could tell me is I needed to go buy a new kit. I just bought this one 6 weeks ago and it was working correctly when I bought it.

Off to Walmart to drop another $13.

Presently I'm not a happy HTH customer.



"So...back to business..... I called hth. Sounded like a high school student on her summer telemarketing job. She had no clue how to help me. She put me on hold and when she came back she told me that I "don't need anymore because I am only supposed to test for CYA 2x a season.".
I laughed. ""
