Ok so I'm slamming because I can't keep any FC in pool and it's very cloudy. I had a new VSP installed and they didn't turn my salt cell back on and I didn't realize it until it was too late. So I started a slam but now am getting a foam like substance on top of water. I also am raising my cya at same time. Could the foam be a reaction to an organic or a reaction to CH? My CH is at 290, it's usually around 320.
