Rick,
I agree that I need to get a test kit. The stores around here (I tried the 4 that I know of) all sell the small kits that don't test for CYA. I know Ben sells them, but I think I should get one fairly soon, and other posts from people who have already ordered tham seem to suggest that they take quite a while to arrive after the order. I'll probably just order from Ben and test at the stores until it arrives. Ben put this whole sits together so ordering from him seems to be the right thing to do to support him and his efforts. I agree with you that the test results are all over th board. I think the results I got yesterday were wrong. My small home test kit agrees with the numbers I got today. My kit only does FC, pH and Alkalinity, but those numbers match. Thanks for the response.
Doug
