pump filter not working

[koagirl]

thanks, I'm guessing it's B (we've been backwashing every day, sometimes multiple times a day because we've had so much algae) didn't know we lost sand when se did that. I'll tell the hubs and we'll check the sand. I'll read the link immediately. Thanks!

You should only backwash a sand filter whenever the pressure rises 8-10 psi over the clean filter pressure.
