Ok so we get a lot of people on here who have fish problems but have a hard time answering the questions about what kind of filter they have and how many GPH they turn over. I have compiled a reference list of all/most of the commonly used filters, their GPH, and the size tank that they're made for. This way it's all in one place for those of us who are trying to analyze and solve some of the problems that pop up so often. Now you don't have to search the entire internet to find out how many GPH such-n-such filter turns over.
