Hello all! I ordered a tank set that came with the Aqua-Tech Power Aquarium Filter w/ 3-Step Filtration for 10-20 gallons. It worked fine yesterday and today is making a very very loud rattling noise after a water change. I can not figure out how to make it stop. It is my first HOB filter and I love it but I cannot handle the loud noise of it. Has anyone had this happen and it was able to be fixed? It is pressed in as far as it can go which was the common google "solution". Thank you in advance!
