Am very excited to have found this site. It looks to be much more user-friendly than my local pool store. I am very new to pool care, and have so far relied on their testing and recommendations for chemicals. This is becoming a financial drain. It looks like the first step should be the purchase of a good test kit. My first question is, of the test kits you have recommended, do I need both the K-2006, and the smaller ( can't remember the number ) one? It looks like the larger kit is for testing everything and the smaller one is for daily use, and test only the basics. Thanks for the help!
