when I said you might want to replace it in a couple of months,i meant like I said..you get what you pay for....the more you look into anything you always find out there is a better way or a better product...I've tried several over my few yrs in this hobby. berlin air lift, better than nothing..then the prizm pro-$99.00 online and i think at *****,not great but works better than some say,I have one on a 45 gal,then my most recent and what I would reccomend to everyone..an aquaC EV model.I have the 180,I dont think you need one that large its on my 125 and rated for 250 gals,they make smaller ones...I just think you might want to go for something really nice the first time because a skimmer can be an important part of equipment.....yet a few go skimmerless so, who knows......
