I have two Marineland Tidepool II (http://www.drsfostersmith.com/product/prod_display.cfm?c=3578+3579+3589&pcatid=3589) sumps for sale.
They are drilled on the side with 2" heavy duty bulkheads (http://www.marinedepot.com/ps_ViewItem~idProduct~FT1149.html) to be used together.

$120 for the pair or $80 for one.

.....actually, I'll take $80 for them both.

still available...

Are they come with S.O.S. Pre-filter?

I am looking for a sump for the 120g that I got from you.
