Have a cheap test kit (plan to get a better one) but it has always "worked" in the past. Now when I add solution #2 to test the ph the water does not change colors. Bought a new bottle of #2, no change. I took a sample to my pool store and the ph was 8.0 so added acid, my test kit showed no reading (clear water), tested again at the pool store was 7.2 so added baking soda. My test kit shows no reading (clear water). I can't keep going to the pool store and not buy anything!
Pool is pretty cloudy but looks good other than that. Any ideas on why I am not gettting a reading on my PH?
