Just for grins, I ordered the Taylor K-1766 salt test that uses silver nitrate (wear plastic or nitrile gloves - Thanks to Waterbear for letting us know the silver nitrate causes BLACK STAINS FOREVER on skin and nails!!). Wanted to get down to the nitty gritty and see how the AquaChek strips held up against this test. Just a little backup test, since I'm trying to really be accurate on my salt levels because of my Intellichlor. Plus, I just like to do water testing! I'm a dork.
Tested today. Results are:
Taylor drop salt test: 3400
AquaChek salt strips: 3590
WooHoo!! The strips are within 5% of the Taylor drop test. So, everybody who's taking their water to the pool store for testing, please get the strips and trust your results (just don't get them wet or damp)!! They work very well. Leslie's tested my water at 3000, much less accurate. One Pentair rep used a digital tester that read 4500. So much better to rely on yourself and TFP!!
