Koralia Help

They are both the Evolution series and both rated for 1400gph. They are the same thing.
 
Different vendor pricing. Kind of like going to your LFS and shoping around. Some better deals at one of the othe.

This is where I bought mine when they had a 50% off sale for christmas last year so you can see the price is still a little different that the other two. Just make sure you get the new version which will hav ethe add on for the mag.
