I just bought the Speedwave 1320 (or DC-5000 which ever name you want to call it) Im finding that if I run it anywhere past level 2, it gives off a high pitch hum which is almost unbearable to be around. With the tank in my living room and the sound im wondering if something is wrong? Im seriously considering going back to an AC motor because its so loud.
Wondering if anyone else has this issue?
