Hmmm. For some reason I did not get the PM you sent, but I did get your note here on your visitor messages...maybe next time try my email
special.k97707@gmail.com. Anyway, comes with sump big enough for 50 gallon...it is running right now and all you need to do is pick it up and plug it in

It does not have a skimmer, the sump is big enough for one though. I have had this tank for four years and never used a skimmer on it. I have had success with SPS and clams that way...just a 10% water change per month. I have not had a chiller on it, simply left lights off on hot days. A 2 liter bottle of water in the freezer went into the sump on really hot days and that covered it. If you want it I can hold it for you (as long as it is paid for) until 6/23. If you want to come see it, my fiance is usually home after four, and I have Fridays off.
