This is my first year with a new pool, and I have been getting excellent advice from everyone here along the way.
Recent test results......
Water is clear and bright, looks great. A couple of weeks ago, I added some calcium chloride to get the CH up a little. Ever since then, we have had these small (maybe 3/8" square or so) "flakes" that show up in the water. I do not recall seeing them floating prior to adding the calcium (though they may have been there). We run our filter 24 hrs per day, yet they are still there.
