M almost ready to give up on this...lol. One of my durst drains is silent, the other is like a loud bong. The quiet one feeds into about 7 feet of one inch pipe. It drops 6 niches then travels about 6 feet then elbows to a 2 foot drop. The noisy one drops straight from the bulkhead into the sump, about a 2 foot drop straight down. Why is one silent but the other gurgles like crazy? I've adjusted the air intake with no luck. I can't have the tank run this loud all the time....
