Hello everyone! My name is David and I am in the big bad pool store business. This is my first year working in the industry, and boy am I glad I found this site sooner rather than later! I have realized just how much misinformation is given by so-called "experts" who are just salesmen in disguise, and have learned enormous amounts thanks to the real experts here! You can look forward to me bothering you lots during the off-season winter.
Edit: By the way, Mizu means water in Japanese! Preferably clean water.
