I'm in the process of SLAM'ing because our FC dropped to 0 and then the pool got cloudy.
We have an auto-cover, and to help(???) the process, I've been keeping it closed during the day. I've read a few threads where people said this was fine if you weren't battling CC, which I'm not.
During the day, we have no FC loss at all (With the cover on). I check the pool as early as I can (Though over the weekend, slept in a little - so around 8 or 9am the pool was checked, and there's no direct sun on it at that hour yet.) I would check it once or twice through the day, and it was perfect. Then I'd check it when I went to bed for the night. At this point, I would open the cover and leave it open for the night.
So all day during the day yesterday, we had 21 FC. This was from about 9am until 9pm with the cover closed. This morning at 7:30am, I'm down to 18.5 FC. This is the second day in a row this has happened.
Water clarity is a 9.5 out of my usual 10 at this point.
Any thoughts? Everything else is in check.
