I'm closing on a house with a pool on Tuesday. Last night we did a walkthrough and I snagged a sample of the pool water. I ran the CYA test as described in my Taylor k-2006 kit but nothing seemed to happen. It sounds like the dot is supposed to disappear because the solution should be cloudy...but mine wasn't cloudy at all after I shook it up. Does it make sense that there would be no CYA in there or did I screw something up? I also didn't get anything showing up on the chlorine test if it's relevant.
