I just bought a top of the line testing kit and oh boy what a shock. Let me back up. I have a nice clear pool but getting a tiny bit of greenish/yellowish algae in the shady side that appears after about a week. Brush it and it goes away but pops up again about a week later. I tested my water and this is what I got. BTW my tap water measures 60 ppm calcium hardness. I am assuming I should drain part of the water but how much. Also I would like to stop using the solid sanitizers and switch to liquid after reading the recommendations on this forum. Any other suggestions would be appreciated. I have owned this pool for 20 years and starting to realize I don't know a heck of a lot about how to maintain it! Thanks.....Mark in Fresno
