How deep should I draw my test sample?
Taylor test kits sayTF Test kits say7. Obtain samples 18" below water surface.I understand that the surface water is going to have oils and pollen and such which could affect the tests. I've been using a piece of PVC pipe like a pipette and draw the sample from a couple inches off the floor in the shallow end, maybe 30" below surface. What's the difference between 12", 18", and 30" from the top? Do the chemicals stratify or something?6. Collect all your pool water samples about a foot under the surface.
