I have beening brewing for only a short time, I am on my fourth beer. I am currently brewing a west coast amber (more hops). The top blew off the primary on day 3. I cleaned and sanitized the top and airlock and put it back on. Then about 8 hours later the airlock was clogged again and I replaced it with a blow off tube. is there any disadvantage to a blow off tube vs. an airlock?
