Okay, more weirdness. A few hours later, I no longer hear the water movement noise coming from my filter, the sight glass by the return valve is clear, and there is no more bubbly haze at all!!

As a side note, why would my readings and that of the Leslie's store for TA consistently be discrepant? They use the same reagents as I do (I use Leslie's), right? This morning my 150 was read by them at 100. This has gone on for years. My reagents were just bought this year, too. ???????

P.S. I never saw any bubbles at the pump basket.
