I just thought I would share this experience from Leslies Pool store, which is local to me. I have a TF 100 test kit and use it accordingly. Having said that I occasionally double check with the test strips just to see what results they offer. So ......, I went into the store asking for the Aquachek strips and the salesman states they only have Leslies own brand. He further claims that I will not find the Aquachek strips anymore because they were bought out by another company. I didn't purchase the strips and went to another store. This store was loaded with the Aquachek and I asked him if they were bought out etc.. He said no, and that he has plenty of stock on the Aquachek.
