I have a chance to get an Eheim 2215 Classic for $45 shipped. I am in the process of setting up a Mini M and was wondering if this filter would be too strong for the tank. I know most people go with the 2213 which is rated at 20 gph less than the 2215. I will have HC, Dwarf Hairgrass, Moss and some stems that are yet undecided. Fish and Dwarf African Frogs will also be present. Any suggestions?
