Placed under my 125 gallon tank and it is noisy as heck with vibration / humming sound. Can hear in the other room 25 feet away and around the Z corners.
My FX5 was put back in and very quiet until you walk by tank you can heat filter running. FX6 no.
Anyone else had this type of issue go on?
What can anyone tell me. Motor going out?
Thanks in advance for input.
