I haven't talked to the filter guys yet, but I plan on it tonight. I will try to bring the pH down and shock the heck out of the pool today.

It's just darn frustrating as I NEVER had any issues with my old DE filter. With it, it would filter everything and ask for more. Backwashing every 5 minutes is not my idea of good filtration.

I have no idea about the new unit as when it was installed my wife got ZERO training and not even a manual, which I had to download. The manual really, really sucks as it doesn't go over anything. I don't even know how to open the unit and look/check the sand or any of that.
