Identifying a skimmer

[LuHockey2]

I have a Coral Life super skimmer that came with the tank that I bought used a few years ago off the board. I was told it is the 220, but I wanted to confirm that its not the 125 before I get my bio-load up. I searched on the unit itself and I dont see any markings, I did see the measurements online that show an inch difference in the height of the two. Does anyone have any other ways of differentiating between the two? I would like to think the measurements are precise along with the manufacturing accuracy, but I would like to have better proof if possible.

Thanks,

Brian

125 Gallon 5" x 7-1/4" x 24-1/2"
220 Gallon 6" x 8" x 25-1/2"

the chamber on the 225 protein skimmer will be bigger also like you said one inch taller. so if yours is 24" 1/2 you habve the 125
