Sorry to hear this hasn't cleared up for you yet. We do see pools where this happens every now and then. There's a lot of speculation about why this happens but nothing proven yet that I know of. My personal belief is that it's most often caused by not staying at SLAM levels long. If you have SLAM level only for an hour or two that means the process is going to take a LONG time. Looking at your logs seems to validate this could be your issue. With your schedule it's not easy to do unless you go waaaay over SLAM levels and this is never recommended as it can cause damage. Is there any way you can get a day that you can test and adjust every couple hours? This might be what it takes. Also is it possible you are cleaning anything in or close to the pool with a cleaner that contains ammonia?
