I had my 46 gallon running for a little over a week and the mag7 i bought from you keeps causing my GFI to trip randomly so much so that b4 i removed the tank from my room i ran with out my sump return for a few day bc i had to unplug it before going to work. I actually took the tank down so i could put something smaller in my room it was a little too loud. Do you know what would cause the mag7 to do this i had only been using it for less then 2 weeks. It was the one Sal sold me from the used section not sure if you remember it probably not but i was wondering what would cause this and what do i need to do? I plugged it up to test it in a bucket of water again today and it it making a wierd sound but the impeller is not broken or cracked??? Was it going bad causing the trip and finally bit the bullet? If so what can i do? Thanks in advance guys yall are always helpful.
