It's great to see a newbie doing everything right! Usually, we all make super-duper mistakes at that time.

Jan and Lisa have guided you correctly.

Until you get the K-2006 you can dilute pool water with distilled water (the "CarlD Patented Shot Glass Method") to boost the range of your HTH chlorine tester.

I like the shot glass because it's not too big, not too small and gives VERY precise dilution. So...1 shot of pool water and 1 shot of distilled water mixed together, then poured into the test block (or "cell") will allow you double the reading you get. If it reads "4", your chlorine is 8.

If you use 2 shots of distilled to one of pool, you triple the reading--therefor if it reads "4" it's really 12.

Hope this helps.
