We really need a full spectrum of numbers (FC, PH, CH, ALK etc.) which you may not be able to post. In order to get a more accurate chlorine reading using your current test kit, take a sample of your pool water and mix it with an equal amount of purified (bottled) water then double the number you come up with. This should expand your test to 6. If it reads 6, then use two parts purified water to one part pool water, this should expand your test to 9. I'm thinking you can at least get your chlorine in order (which may be the culprit) while waiting for a good test kit.
