I had this on my 29 gallon quarantine tank, it's about 5-6 months old. It works perfectly fine I just need one for my 20 gallon now and sadly this doesn't fit under my tank . I can do 80 shipped to your house (within the usa), the cheapest you are going to find online is 109 shipped to your house. And this skimmer never had any chemicals like copper or any medication the tank was dosed with B Ionic that was it. Picture is below (Note: the shoe nor the scissors come with the skimmer )
