How can you tell which koralia you just bought?

I purchased a 1400 off of reef2reef and it doesn't seem like it puts out 1400 gph I tried to look up specs and all of them have the same size housing?

The color of the impeller should tell you which one you have. Like my 2's have an orange impeller and my 4 has a green impeller. Not sure about the other ones.

If you have a newer koralia than the sticker tells you. But it falls off after 6 months so your sol now. I'm in the same boat. I kept the box's to prove it of I need to some day.
