Starting a new 75g freshwater tank for African Cyclids. In your experience which is the better filter: Filstar XP3, Eheim 2217 or Magnum 350 Pro? . I can get both the Eheim & XP3 for the same price @ Ken's $137. The 350Pro is $106.00 Can I make this the only filter on my tank (if its not overstocked?)
