I had a Jebo hob skimmer on my 180. All I ever heard was bad things about them but I found: It was very quiet, The only sound was water going down a ramp about 2". It pulled about a cup of thick black goo every 4-6 days. It never leaked, not even a little bit. It was very easy to adjust. It cost me $30 on E-bay. I now have a bigger skimmer but I am keeping the Jebo for a future cube or something. These are my experiences yours may differ. I liked my Jebo
