Rattling Xtrol pressure tank

[smithwd]

When my well pump cycles and starts filling my Xtrol tank it sounds like marbles rattling around inside the tank...

Any ideas? it fills fine,,just noisy

Check the air charge to be sure, but quite a few of them make that noise. Is there a check valve in the inlet? If so, that's what's rattling

thanx for the info..
pressure goes up to 60 with a faucet open.......when it hits 60 it does a quick drop to 50 and then continues normally until it hits the low setting.
