In the past week my pool water has been consistently cloudy. Brushing the bottom shows a fine brownish layer but water chemistry all looks to be good as far as I can tell (see below). Overnight loss of FC is <1ppm, I am attempting my first SLAM, keeping FC up at 15, running the filter continually and brushing twice a day. Is there anything else I should be doing? Is this likely to be algae?
The water does not seem to have changed at all since starting 3 days ago, blue water but cloudy with some fine sediment at the bottom. I do live next to a fairly busy road so I thought at first it was just dirt being kicked up from the road accumulating since my cover has been off for a few weeks since it's been so hot.
