I cleaned my cartridges about a month ago, right after we moved into the house. The pressure once I reinstalled everything was about 17-psi which was higher than I expected it to be after cleaning them. Over the past 4 weeks the pressure on the gauge has been slowly dropping. Last night it was hovering right around 15-psi. I'm not sure if I should pull everything apart and see if the filters are still clean or if they are dirty. Water is still very clean and flow at the returns is good. I haven't noticed a decrease in flow coming from the returns since cleaning the filters or anything like that. Any thoughts?
Filter pressure dropping

If it dropped way down I'd break it apart and inspect it, but a couple of pounds isn't a big deal. The gauge could change that much without the pressure actually changing.
I'll keep an eye on it. I don't like to obcess about things, but not having a ton of pool experience (little over a month now) I questions things. Thanks.
Falling pressure usually indicates a water supply issue on the inlet side of the pump or a damaged filter element. A dirty filter would cause a pressure rise.
