Hello, I just joined your site. My name is jvette. I am willing to give the BBB method a try this year because I'm sick of the expense of maintaining my pool. I ordered the TF-100 test kit but I'm not the brightest bulb on the tree. I will need a lot of help getting started and it looks like this is the place to get it. I need to learn quite a lot even before I take my first test. I feel almost relieved now that I've found this. Thank you. jvette.
