Hello, I have a 20 gallon tank with a tetrawhisper filter and it worked completely fine the first week or so, but it has started to kind of overflow. Water comes out of the little spout like it’s supposed to but it also pours out over the tube that suctions the water. When I take the top of there is a bunch of water overflowing. It also has been making weird noises as well. I have turned it off and on again hoping that would help but it didn’t. Any suggestions?
