For sale is a VERTEX-IN180 (in-sump) skimmer that was bought 4 months ago and 2 months in use. Had to move, sold my 180 gallon setup and that's what's left. Worked beautifully, easy to use, very (very) quiet and efficient. More info here:

Paid around $300 for it.
I am located at Surrey Central/SFU in Surrey, BC (Greater Vancouver Area).
