If you are comparing it to a Maxi Jet you can't because it is not a directional flow like they are.. They are a dispearsed flow. If you got these for your 65 you underbought. I would have purchased #3's or #4 and #2 depending on how you wanted the flow to be in your tank. I have 2 #3's in my 75 and absolutely love them won't ever switch back. I have no dead spots.
Here is a vid that I did when I only owned one.. The difference between the 1200 and the Koralia #3
