I have an extra collection cup and carbon tray to go with it. All you need to due is put it in the sump and plug it in.No shipping, Make an offer or tell me what you got to trade. Located in NJ.
The Skimmer is about a year old,but only used maybe 5 months, it is rated for up to a 250 gallon tank. I don't know that I would use it on such a big tank , but it worked on my 120. You would have no problem on a 75. http://www.redseafish.com/Product.asp?dir=&catID=93&subID=35&proID=125 you can read up on it here.
