I have one brand new never used marineland in sump skimmer 100 model. I have used the exact same model in the past and it works well and is a plug in and play model. It has a small foot print and will fit in almost any sump. It is still in the box and i never ended up needing it. Here is a link to the exact same model with pictures and a description.

I paid $200.00 plus tax but i will take $150.00 and i am willing to ship it to wherever in canada.
PM for more details
