Hello,
We schocked our pool yesterday and did a backwash before that. Since then the needle on the pressure gauge is oscillating and the filter is making a vibration and a humming noise. There are some air bubbles in skimmer basket but it is full and everything else seems to work fone. What should we do now? Can we backwash again today?
