Yeah... all seems to be in order. We've only been swimming twice this year thus far. We run the filter pump 12 hours per day, which is what we've always done, although recently we've had it on boost mode and ran it solid for a couple of days. We've tried about everything we know to do. I think something might be bummed out on our unit, but I'm just not sure.

Either way it appear we are about to have to spend money on chemicals to get it right. I get frustrated when I spend this much money and it works fine for almost 2 years and then I have to start spending money again.
