So this might be a silly question, but it will help settle my anxiety/OCD. The way I test my water is by filling a plastic cup, which is and always has been used solely for testing water and never used to drink from or washed or anything like that, from about a foot below the surface of the water, then bringing the cup inside to do my testing. Is the water sitting in the cup, then going into the testing tube going to affect my numbers at all as opposed to just directly filling the tube from he pool?
Like I said, probably a silly question. Just wondering if anyone else does something like this or if the experts here think this is fine.
