Just out of curiosity, how does everyone take their samples for pool store testing and what do you store the sample in??
I am rather dirt poor at the moment and can't afford more than the test strips for a while. I haven't ever taken a sample in to a pool store and am wondering what folks use to hold their sample when they do. Do you use virgin containers and take care to fill completely without air (preventing pH shifts?) or just use whatever left over waterbottle container is at hand?
My day job sometimes involves pH adjustments that are far tighter in range than pool care could ever be. I will admit to taking the odd sample into work to test for pH. It's really the only variable I can measure to what level I consider accurate. I just always wonder when I see folks post test results from their PS and their own readings, how much the delay in testing results in a change in the testing results...
