I just started using a false bottom purchased from moreBeer. It's dome shaped so the outer circumference sits flat on the bottom of my roundstyle cooler. Aside from taking much longer to clear my runnings then with my original SS hose braid, I noticed that through-out my entire fly-sparge I was still getting some grain bits flowing through. I would say a couple "bits" every few seconds. Is that normal for these false bottoms?
(it was also my first time fly sparging)
