Hello Everyone! After going back and forth for 12 years we finally decided to take the plunge and build our first pool in Katy, Tx (Houston area)! It is 15,000 gallons, gunite, pebble tech. We are so excited but as many of you, afraid of the water maintenance part. About to order my test kit and wanted to know what are your suggestions? I am thinking of the Taylor Kit. I thank everyone in advance for all the help and suggestions along this journey. Thanks!!
