They haven't even starting digging my pool yet (Hopefully next week), and I am obsessed already about reading pool school and worrying what may go wrong as soon as the water goes in. My wife thinks I'm crazy! I already bought my test kit, working on excel spread sheets, reading everything I can get to on the internet. You guys won't be able to get rid of me when things go south for some reason. I will be home every second that my PB is on site working (he probably won't like that), I got 360 foot of asphalt driveway for concrete trucks to back down (No other way in), got 5,000 gallon tanker trucks bringing water and just know what's going to happen to it. I know I am worrying to much, but thank GOD for this forum!!!
