My pool was installed a couple of weeks ago and for the past week I have been maintaining the chemicals. I have the Taylor K-2006 and have been testing and adding (mostly acid and bleach) to keep my numbers in check. I have the exact numbers at home but I have to admit for my last pool I had a chemical service only but the pool was nice but I don't think it was ever this clear. I have incentive now to maintain and have been checking chemicals every evening and adding about a gallon of bleach each evening. I'm shocked. I was at my brother in law's house this weekend and his pool looked "green" by comparison. Here are a couple of pictures with the water this clear you can see the individual specs in the Pebble Tec.
