I've had the Ecco 2236 for almost six months. I have cleaned the filter once (recommended every 3-4 months), and it's run like a champ. Recently however, about every 5-6 minutes I hear a whooshing sound. If anyone has one of these filters, do you know what that sound indicates? Nothing in the maintenance section regarding cleaning the filter or maintaining the pump head says anything about a rushing water sound. I'll contact Eheim if no one has ever had this experience. Other than this, my other Ecco running a 29 gallon tank is wonderful. These filters are so simple to set up, clean, and run that I'd recommend them to anyone starting out with cannisters.
