Is there any reason that after adding muriatic acid to the pool, filter pressure may increase?
I’ve noticed this happen every once in a while. My pump runs on low 24/7 (and high for a few hours as well), and I have a spa spillover. Once the flow over the spa starts reducing to a trickle, it’s usually time to backwash. But often this seems to happen right after adding a few cups of acid.
It’s not a problem… I’m just curious what could maybe be happening to cause it.
