I noticed a loud gurgling sound coming out of my return into my poop with extra bubbles. I then noticed the water line of the pool looked low (and spa high). So I looked at the skimmer and noticed water was pouring into it whereas normally it’s just sitting in there.

I turned off the pump and it refilled. So it seems like it’s more empty when the filter is off than on.
Do I have a leak? It hasn’t rained in 2 days.

I turned off the skimmer drain and went 100% main drain, and then started sharing a screeching noise. So I turned the pump off for now.
Coincidentally I’m getting my pool resurfaced in a month since it’s 20 years old so maybe I don’t need to try to address it sooner.
