Looooong fermentation

[12ozrebel]

Fellow brewers,
I am currently brewing an Ale that has been
In primary for 18 days now and its still bubbling
Around every 15-19 seconds. I have not
Experienced a primary fermentation this long.
Should I be concerned?
Cheers! 12ozrebel

What's the current gravity?

It's probably been finished for a while, and is just bubbling/off gassing. If the SG hasn't changed in the last 5 days or so, it's not going to change.

Thanks for the quick replies.
