UV filter pressure gauge seems to be too low

We left our “shark” in overnight and when we took it out it seemed to affect our UV filter. Normally the filter runs around “10” on the pressure gauge but now it’s running at around “2”. The only time we’ve had issues with it in the past is when our pool water level was too low but that isn’t the case this time so I’m not sure what the problem is.

    Ange, I believe you have 2 pressure guages. 1 on your UV unit and 1 on your System 3 filter. What does the other guage read? That will help us with better advice for you.

    The other gauge reads 19 when its usually at around 12
