I'm just wondering if I'll have inaccurate results if I test my water too soon after a rainfall. Yes, I always take my samples from an arm's length depth, so not to test the water that's "on top". I just have a feeling that I'm flying through my first TF-100 kit since opening the pool, and I don't want to waste any of it if I can help it. Thanks for any help.
