Hello everyone, I recently upgraded from a 20 Gallon tank to a 60 Gallon tank. In the 20 gallon tank i used the Aqueon 20/30 Filter. I liked it so much because it was super quiet, and didn't annoy the frogs at all. With this new 60 Gallon tank, I bought the Aqueon 55/75 filter. I'm not too impressed with it. It makes this grinding noise periodically, it annoys the frogs, and particularly it annoys me when it does this. I"m thinking of getting rid of this particular Filter, and wondering if Getting 2 of the Aqueon 20/30 Filters in place of this one would be beneficial. I welcome any and all comments, suggestions, from the peanut gallery.
