Welcome to TFP. First question is your kit. You did get the K-2006 right. Why I ask is you said it was the DPD kit and that would be the K-2005. The 2006 FAS-DPD is a good kit and will give you accurate tests that this site uses. Start with the CYA test outside with the sun to your back. Do the test, put it back into the little mixing bottle and run the test several times. You can only get a few full CYA test from the 2006 kit. Don't really worry about the book that came with the kit. It is based on "pool store" thinking. Follow the instructions under the lid to get your numbers and then use pool math. You can also look at the youtube channel for help doing the test. The youtube is based off the TF-100 kit. The test are all done the same. The K-2006 has one test block. Half is for CYA, the other side is for FC,pH,TA,CH.
What we teach is you learning :lookhere: *YOUR* pools personality. They are all just a little different, even between neighbors or local pools. Once you learn what your pool needs, you only add whats needed to be corrected. I do not "shock" my pool weekly, can't tell you the last time I had to do a full slam. With that cost taken out the savings add up. For your immediate questions, keep it in this thread. It will keep all your other information here and we can refer back to it. Once you run a full set of number and get a hand on things if you have a new question then yes start a new tread. Good luck. It's might seem like a lot of information but it is very easy to learn if taken in steps.
