I have an Eclipse tank set up as my QT and I've noticed that the pump makes a very loud humming/buzzing sound. It seems like the pump goes through a "cycle" about every hour or so. It starts out as a soft hum and then gets louder and louder. This lasts for about 2 minutes then it shuts off. I'm wondering if this is a normal sound for this type of tank or if it is defective? Is this sound stressful/harmful to the fish?
