StoneScape "touch of glass" and color recommendations? Newby.

There could be your problem :( The guess strips are worthless :( Go ahead and throw them away. They cause more harm than good in the long run with bad/off readings. Pool stores=only as good as the effort and skills the tester has. I have seen how bad they can be as they "helped" me ruin a liner with their testing and advice.

Here is some reading for you: Test Kits Compared give these kits a look and pick one to buy please.
