I just put on the new Nautalus TE (sp?). it uses a rio 2500 for power, is more then capable of upto 300 gal tank, I run it on the 125,. and have to empty the large collection cup once a week or so.. I like it..
downside is size. It is huge 24' high, and my sump is in the stand. in the tidepool II filer. it's also about 8 inches in diameter.
