I updated this yesterday but apparently I didn't submit the reply. Anyway, I checked the chlorine level yesterday morning and had no chlorine loss, so it doesn't seem to be fighting off any algae but is still cloudy. I actually got in there today to remove my steps. Was a little chilly at 70 degrees. I manually vacuumed under the steps, and gave the walls a good brushing again. Floor and walls are clean enough for closing now but I would really like to make the cloudiness go away before covering it. I plan to close next Saturday. Any further help would be appreciated. I'm thinking I'm going to bring it to shock level tonight anyway unless someone tells me otherwise before then. Thanks!
