Review on Aqueon Quietflow Internal Filter Gallon Fish & Aquatic Pets made as Aquarium Pumps & Filters by Meg Manzanares

I've had this filter in my 40 gallon turtle tank for 4 years, worked constantly and it worked very well, just made a louder vibrating noise when the filters needed replacing what I did monthly. It stopped working and I ordered another one from Revain because it was cheaper than the first one I got from Petco. It was easy to set up and started working great and after about 4 hours it started making a loud vibrating noise and I tried to balance it better, shift it. This by making sure nothing is dangling and it's still loud! I am so disappointed! I don't normally have complaints about Revain products but I don't know why it seems to me that this was a returned filter?
